Product details
Overview
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), 5mA supply current per comparator, shutdown mode consuming only 270μA per comparator, and Beyond-the-Rails™ input range extending 100mV beyond both rails. It is used in high-speed sampling circuits and GPS receivers where precise, low-latency threshold detection is required.
For engineers reviewing the MAX964EEE datasheet, MAX964EEE pinout, MAX964EEE application, or MAX964EEE equivalent, key selection considerations include its quad-channel configuration, QSOP-16 package, shutdown capability, TTL/CMOS-compatible outputs, and guaranteed 0.52V rail-to-rail output swing under 4mA load.
Technical Context
The MAX964EEE implements a current-driven output stage enabling fast slew rates and rail-to-rail output swing within 0.52V of GND and VCC while sinking or sourcing 4mA. Its internal 3.5mV hysteresis eliminates external feedback components and prevents oscillation near trip points.
It uses a differential input stage with 200Ω series resistors and front-to-back diode clamps to protect against ±3VF differential overvoltage, supporting robust operation in noisy environments. The device supports shutdown via a high-impedance SHDN pin, reducing supply current to 270μA per comparator and placing outputs in high-Z state.

Pinout & Package
MAX964EEE is housed in a 16-pin QSOP package (package code E16-1), RoHS-compliant, with 0.65mm lead pitch and 5.0mm × 4.0mm body size. Thermal derating is 8.33mW/°C above +70°C (667mW max at TA = +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | N.C. | No internal connection; must be left unconnected or tied to GND to prevent parasitic coupling |
| 2 | INA− | Inverting input for Comparator A - accepts signals up to 100mV beyond rails |
| 3 | INA+ | Noninverting input for Comparator A - differential pair with INA− defines A-channel decision threshold |
| 4 | GND | Analog/digital ground reference - requires low-inductance plane for high-speed stability |
| 6 | INB− | Inverting input for Comparator B - electrically isolated from other channels to minimize crosstalk |
| 7 | INB+ | Noninverting input for Comparator B - supports independent threshold setting per channel |
| 8 | INC− | Inverting input for Comparator C - shares same input stage architecture as A/B for matched performance |
| 9 | INC+ | Noninverting input for Comparator C - enables three independent high-speed decision paths |
| 10 | IND− | Inverting input for Comparator D - completes quad-channel functionality with rail-to-rail input support |
| 11 | IND+ | Noninverting input for Comparator D - allows simultaneous monitoring of four analog signals |
| 12 | QC | Output for Comparator C - TTL/CMOS-compatible, capable of 4mA sink/source |
| 13 | QD | Output for Comparator D - high-speed output with 2.3ns rise/fall time (VCC = 5V) |
| 14 | SHDN | Active-high shutdown control - high-Z outputs and 270μA quiescent current when asserted |
| 15 | VCC | Positive supply input - must be decoupled with 0.1μF ceramic capacitor placed adjacent to pin |
| 16 | QA | Output for Comparator A - primary output; QB/QC/QD follow same electrical specs |
Key Features

FAQ
What is the maximum operating temperature range for MAX964EEE?
The MAX964EEE is specified over the −40°C to +85°C industrial temperature range. This rating applies to all E-grade devices in the MAX961–MAX964 family, including MAX964EEE. Operation outside this range is not guaranteed, and thermal derating must be applied above +70°C per the 8.33mW/°C specification.
Does MAX964EEE require external hysteresis resistors?
No, MAX964EEE does not require external hysteresis resistors. It includes a fixed 3.5mV internal hysteresis to prevent oscillation near switching thresholds. This eliminates the need for external feedback networks, simplifying layout and improving consistency across temperature and voltage variations.
Can MAX964EEE drive standard TTL or CMOS logic directly?
Yes, MAX964EEE can drive standard TTL and CMOS logic directly. Its outputs are TTL/CMOS-compatible, delivering VOH ≥ VCC − 0.52V and VOL ≤ 0.52V while sinking or sourcing up to 4mA - meeting input voltage thresholds and fan-out requirements of 74HC, 74AHC, and similar logic families without level-shifting circuitry.
What is the function of the SHDN pin on MAX964EEE?
The SHDN pin on MAX964EEE is an active-high shutdown control. When pulled high, it disables all four comparators, reducing supply current to 270μA per comparator and placing all outputs in high-impedance state. For normal operation, SHDN must be tied to GND. Exit from shutdown requires LE to be low (though MAX964EEE has no latch-enable function).
Is MAX964EEE pin-compatible with other devices in the MAX96x family?
No, MAX964EEE is not pin-compatible with other MAX96x devices. It uses a 16-pin QSOP package with dedicated pins for four independent comparator inputs and outputs, whereas MAX961/MAX962 use 8-pin μMAX/SO and MAX963 uses 14-pin SO. Pin mapping differs significantly across variants due to channel count and feature set differences.
