Product details
Overview
MAX964EEE+T from Maxim Integrated is a quad ultra-high-speed comparator with internal hysteresis, optimized for single +3V or +5V operation. It features 4.5ns propagation delay (5mV overdrive), ±3.5mV input-referred hysteresis, rail-to-rail beyond-the-rails input range (–0.1V to VCC + 0.1V), and shutdown mode consuming only 270μA per comparator. It is used in high-speed sampling circuits and GPS receivers where precise, low-latency threshold detection is required.
For engineers reviewing the MAX964EEE+T datasheet, MAX964EEE+T pinout, MAX964EEE+T application, or MAX964EEE+T equivalent, key selection criteria include quad-channel count, 16-pin QSOP package, shutdown capability, TTL/CMOS-compatible outputs, and guaranteed 4.5ns propagation delay at 5mV overdrive under –40°C to +85°C operation.
Technical Context
The MAX964EEE+T implements a current-driven output stage enabling fast slew rates while maintaining VOH ≤ VCC – 0.52V and VOL ≥ 0.52V at 4mA load. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points.
It supports shutdown via SHDN pin (active-high), reducing supply current to 270μA per comparator and placing outputs in high-impedance state. Unlike MAX961/MAX963, it lacks latch-enable functionality but retains complementary output capability per channel - though MAX964 specifically provides non-complementary outputs as confirmed in the Selector Guide.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision latency in timing-critical sampling paths |
| Supply Voltage Range | +2.7V to +5.5V - supports both 3V and 5V single-supply systems without level-shifting |
| Input Common-Mode Range | –0.1V to VCC + 0.1V - allows direct sensing of signals beyond supply rails, e.g., battery voltage monitoring |
| Output Drive Capability | Sinks/sources 4mA to within 0.52V of GND or VCC - drives standard TTL/CMOS loads without external pull-ups |
| Shutdown Current | 270μA per comparator - reduces total system quiescent power by >95% during idle periods |
| Hysteresis | 3.5mV input-referred - suppresses noise-induced chatter without requiring external resistor networks |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable equipment environments |
Pinout & Package
MAX964EEE+T is housed in a 16-pin QSOP (Quad Small Outline Package) with 0.15mm lead pitch and RoHS-compliant lead-free finish ("+" suffix). The package measures 4.9mm × 3.9mm × 1.45mm and is compatible with standard surface-mount reflow processes.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA− | Inverting input for Comparator A - accepts signals down to –0.1V relative to GND |
| 2 | N.C. | No connection - internally unconnected; tie to GND to prevent parasitic coupling |
| 3 | INA+ | Noninverting input for Comparator A - supports common-mode voltages up to VCC + 0.1V |
| 4 | QB | Output for Comparator B - TTL/CMOS-compatible, active-high, high-impedance in shutdown |
| 5 | VCC | Positive supply input - must be ≤ +5.5V; decoupling capacitor required adjacent to pin |
| 6 | GND | Ground reference - low-inductance plane connection critical for high-speed stability |
| 7 | QC | Output for Comparator C - matches QB electrical characteristics and timing behavior |
| 8 | QD | Output for Comparator D - identical drive strength and propagation delay to QA/QB/QC |
| 9 | SHDN | Active-high shutdown control - pulls high to enter low-power mode; requires clean logic transition |
| 10 | INC− | Inverting input for Comparator C - electrically isolated from other inputs; shares same hysteresis profile |
| 11 | INC+ | Noninverting input for Comparator C - differential pair matched to INA+/INA− for consistent offset |
| 12 | IND− | Inverting input for Comparator D - independent input path with same ESD protection structure |
| 13 | IND+ | Noninverting input for Comparator D - maintains <0.3ns inter-channel skew across all four comparators |
| 14 | INB− | Inverting input for Comparator B - referenced to same internal bias network as other channels |
| 15 | INB+ | Noninverting input for Comparator B - supports simultaneous multi-threshold detection with minimal crosstalk |
| 16 | QA | Output for Comparator A - primary output; synchronized with QB/QC/QD within 0.3ns skew |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast 4.5ns propagation delay | Enables real-time signal edge detection in GPS baseband and high-speed data acquisition |
| Beyond-the-Rails™ input range | Accepts inputs 100mV below GND or above VCC - eliminates need for level-shifting in battery-monitoring circuits |
| Integrated 3.5mV hysteresis | Removes external resistor networks and associated board space, layout sensitivity, and temperature drift |
| Shutdown mode (270μA/comparator) | Reduces total quiescent current to <1.1mA for quad configuration - extends battery life in portable systems |
| TTL/CMOS-compatible outputs | Directly interfaces to FPGA I/O banks and microcontroller GPIO without external buffers or level translators |
| 16-pin QSOP package | Provides compact footprint (4.9 × 3.9 mm) with sufficient pin separation for high-speed routing and thermal relief |
Applications
| GPS Receiver Front-End | High-Speed Data Acquisition |
|---|---|
Use Scenario: Detecting zero-crossings and timing edges in L1-band IF signals after quadrature downconversion. IC Role / Device Role / Timing Role: Quad comparator simultaneously monitors I/Q channel thresholds to generate synchronous clock recovery pulses and symbol timing markers. Use Value: 4.5ns propagation delay ensures sub-10ns timing uncertainty in pulse generation, directly improving bit-error-rate performance in weak-signal conditions. |
Use Scenario: Converting analog sensor outputs (e.g., photodiode arrays, RF envelope detectors) into digital event triggers for time-of-flight or peak-detection systems. IC Role / Device Role / Timing Role: Four independent comparators implement parallel threshold windows for multi-level amplitude discrimination. Use Value: Matched propagation delay (<0.3ns skew) across all channels guarantees deterministic timing alignment between parallel decision paths. |
| Portable Battery Monitor | Industrial Line Receiver |
Use Scenario: Monitoring cell voltage, charge/discharge current sense, and thermal cutoff thresholds in handheld medical or test equipment. IC Role / Device Role / Timing Role: Simultaneous voltage window detection on multiple battery cells using shared VCC/GND with independent IN+/IN− pairs. Use Value: Beyond-the-Rails input range allows direct measurement of voltages slightly below GND (e.g., shunt-based current sensing) without op-amp front-end. |
Use Scenario: Receiving differential RS-422/RS-485-like signals in factory automation controllers where EMI immunity and fast response are critical. IC Role / Device Role / Timing Role: High-speed comparator converts noisy line signals into clean logic levels before FPGA-based protocol decoding. Use Value: 3.5mV internal hysteresis rejects broadband noise without degrading rise/fall time - maintains 2.3ns edge fidelity even with 50mVpp interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339AQDRQ1 | Slower (1.3µs propagation delay), no internal hysteresis, no shutdown, wider supply range (2V–36V) | Automotive-qualified; suited for low-speed, high-voltage industrial monitoring - not viable for GPS or sampling circuits | Select only when speed <100ns is acceptable and rail-to-rail input is unnecessary |
| ADCMP572BCPZ-REEL7 | Faster (2.5ns), ECL/PECL outputs, no internal hysteresis, no shutdown, requires dual supplies (–5.2V/+5.2V) | Targeted at RF test equipment and optical receiver modules - incompatible with single 3V/5V logic domains | Choose only for ultra-low-jitter applications with dedicated ECL infrastructure and no power-constrained operation |
Compared with LM339AQDRQ1 and ADCMP572BCPZ-REEL7, MAX964EEE+T uniquely balances nanosecond-speed decision latency, single-supply operation, integrated hysteresis, and low-power shutdown - making it the only option suitable for portable, battery-powered, high-sample-rate systems requiring deterministic timing and minimal external components.

FAQ
What is the operating temperature range for MAX964EEE+T?
The MAX964EEE+T is specified for operation from –40°C to +85°C, meeting industrial-grade environmental requirements. This range is explicitly confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables for all E-grade devices including MAX964EEE+T. The "E" suffix denotes this extended temperature qualification, and the "+" indicates RoHS-compliant packaging.
Does MAX964EEE+T support latch-enable functionality like MAX961 or MAX963?
No, MAX964EEE+T does not include latch-enable functionality. Per the Selector Guide and Pin Description table, latch-enable (LE) is only present on MAX961 and MAX963. MAX964EEE+T has no LE pin and no internal latch circuitry - its outputs respond immediately to input transitions without storage capability. This is a deliberate functional distinction within the family.
What package type and dimensions does MAX964EEE+T use?
MAX964EEE+T uses a 16-pin QSOP (Quad Small Outline Package) with package code E16-1. Its dimensions are 4.9mm × 3.9mm × 1.45mm, and it features a 0.635mm lead pitch. The "+" suffix confirms it is lead(Pb)-free and RoHS-compliant, and land pattern number 90-0167 applies for PCB layout.
Can MAX964EEE+T operate from a 3.3V supply?
Yes, MAX964EEE+T fully supports 3.3V operation. Its supply voltage range is +2.7V to +5.5V, and all key specifications - including 4.5ns propagation delay, 3.5mV hysteresis, and output drive strength - are guaranteed across this range. Electrical Characteristics tables explicitly list data at VCC = 3.0V and 5.0V, confirming robust 3.3V compatibility.
How does the shutdown mode affect output states on MAX964EEE+T?
When SHDN is driven high, MAX964EEE+T enters shutdown mode: supply current drops to 270μA per comparator, and all four outputs (QA–QD) enter high-impedance state. Outputs remain floating - no pull-up or pull-down is activated internally. To ensure defined logic levels during shutdown, external termination resistors must be added at the system level if required.
