Product details
Overview
The MAX964EEE+ 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, noise-immune threshold detection is required.
For engineers reviewing the MAX964EEE+ datasheet, MAX964EEE+ pinout, MAX964EEE+ application, or MAX964EEE+ equivalent, key selection considerations include its 16-pin QSOP package, quad-channel architecture without complementary outputs, shutdown control via SHDN pin, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX964EEE+ implements a current-driven output stage enabling TTL/CMOS-compatible sourcing/sinking of 4mA within 0.52V of either rail. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points.
It uses a dedicated SHDN pin to place all four comparators into high-impedance shutdown state with 270μA total supply current. Unlike MAX961/MAX963, it lacks latch-enable functionality and complementary outputs-its four outputs (QA–QD) are single-ended TTL-compatible signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision timing in high-speed data acquisition |
| Supply Voltage Range | +2.7V to +5.5V - supports direct interface with modern low-voltage logic and battery-powered systems |
| Input Common-Mode Range | –0.1V to VCC + 0.1V - allows detection of signals below GND or above VCC without level-shifting circuitry |
| Supply Current (Active) | 5mA per comparator at VCC = 5V - balances speed and power for portable instrumentation |
| Shutdown Current | 270μA per comparator - reduces system standby power by >95% vs active mode |
| Input-Referred Hysteresis | 3.5mV - provides deterministic noise margin without external components |
| Output Drive Strength | Sinks/sources 4mA to within 0.52V of GND/VCC - directly drives standard TTL/CMOS loads without pull-ups |
Pinout & Package
The MAX964EEE+ is housed in a 16-pin QSOP (Quad Small Outline Package) with 0.154" body width and 0.025" lead pitch, RoHS-compliant and lead-free.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA− | Inverting input for Comparator A - differential pair node with Beyond-the-Rails capability |
| 2 | N.C. | No connection - internally unconnected; tie to GND to prevent parasitic coupling |
| 3 | INA+ | Noninverting input for Comparator A - accepts signals down to –0.1V or up to VCC + 0.1V |
| 4 | INB− | Inverting input for Comparator B - electrically identical to INA−, independent channel |
| 5 | INB+ | Noninverting input for Comparator B - fully differential input pair with internal hysteresis |
| 6 | INC− | Inverting input for Comparator C - shares same input stage architecture as A/B channels |
| 7 | INC+ | Noninverting input for Comparator C - supports high-CMRR operation up to 1.0mV/V |
| 8 | IND− | Inverting input for Comparator D - fourth independent comparator input pair |
| 9 | IND+ | Noninverting input for Comparator D - enables simultaneous 4-channel threshold monitoring |
| 10 | QD | Output for Comparator D - TTL/CMOS-compatible active-low or active-high depending on input polarity |
| 11 | QC | Output for Comparator C - open-drain capable via external pull-up; sinks 4mA minimum |
| 12 | QB | Output for Comparator B - no complementary output; single-ended logic-level signal |
| 13 | VCC | Positive supply input - must be ≤ +5.5V; decoupling capacitor required adjacent to pin |
| 14 | GND | Ground reference - low-inductance plane connection essential for high-speed stability |
| 15 | QA | Output for Comparator A - primary output; transitions within 4.5ns under 5mV overdrive |
| 16 | SHDN | Shutdown enable input - logic-high disables all comparators and forces outputs to high-Z |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast 4.5ns propagation delay | Enables real-time decision making in GPS baseband processing and high-speed ADC front-ends |
| Beyond-the-Rails™ input range | Accepts inputs 100mV below GND or above VCC - eliminates need for external level shifters in sensor interfaces |
| Internal 3.5mV hysteresis | Prevents chatter during slow-moving or noisy input transitions - no external resistor network required |
| Shutdown mode (270μA/comparator) | Reduces quiescent current by >95% - critical for battery life in portable test equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Slower (1.3µs propagation delay), no internal hysteresis, wider supply range (2V–36V), no shutdown mode | Used in low-speed industrial controls; unsuitable for GPS or sampling circuits requiring nanosecond response | Select LM339DR only when cost sensitivity outweighs speed/hysteresis requirements and shutdown is unnecessary |
| TLV3502IDR | Faster (4.5ns), dual-channel only, no shutdown, 1.8V–5.5V supply, rail-to-rail inputs but not Beyond-the-Rails | Used in low-voltage portable systems; requires two devices to match MAX964EEE+'s quad density | Choose TLV3502IDR when operating below 2.7V or when board space permits dual placement and shutdown is not needed |
Compared with LM339DR and TLV3502IDR, the MAX964EEE+ uniquely delivers quad-channel, nanosecond-speed, Beyond-the-Rails operation with integrated hysteresis and shutdown - enabling compact, low-power, high-precision threshold detection in space-constrained RF and instrumentation designs.

FAQ
What is the operating temperature range for the MAX964EEE+?
The MAX964EEE+ is specified for operation from –40°C to +85°C. This E-grade temperature range is guaranteed across all electrical parameters in the datasheet, including propagation delay, input offset voltage, and supply current. The device uses standard silicon process technology and does not include extended-temperature variants like the MAX999AAUK+.
Does the MAX964EEE+ support complementary outputs?
No, the MAX964EEE+ does not provide complementary outputs. Unlike the MAX961 or MAX963, which offer Q and Q̅ outputs per channel, the MAX964EEE+ provides only single-ended outputs (QA–QD). Each output is TTL/CMOS-compatible and capable of sinking or sourcing 4mA, but no inverted counterpart is available on-package.
How is the shutdown function implemented on the MAX964EEE+?
The MAX964EEE+ uses a dedicated SHDN pin (Pin 16) to enter shutdown mode. When SHDN is driven logic-high, all four comparators disable, supply current drops to 270μA per comparator (1.08mA total), and all outputs go high-impedance. Normal operation resumes when SHDN is pulled low; no latch-enable or timing constraints apply during wake-up.
What package type is used for the MAX964EEE+?
The MAX964EEE+ is supplied in a 16-pin QSOP (Quad Small Outline Package) with 0.154" body width and 0.025" lead pitch. The "EEE" suffix explicitly denotes the QSOP package per Maxim's ordering guide, and the "+" indicates RoHS-compliant, lead-free construction. Land pattern number 90-0167 applies.
Can the MAX964EEE+ operate from a 3.3V supply?
Yes, the MAX964EEE+ operates over a supply range of +2.7V to +5.5V, fully supporting 3.3V nominal systems. At VCC = 3.3V, propagation delay remains ≤8.5ns (guaranteed over temperature), output high/low voltages meet TTL thresholds (VOH ≥ 2.78V, VOL ≤ 0.52V), and supply current per comparator is ~5mA - making it ideal for modern 3.3V FPGA and microcontroller interfaces.
