Product details
Overview
The MAX964ESE+ 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 - used in high-speed sampling circuits and GPS receivers.
For engineers reviewing the MAX964ESE+ datasheet, MAX964ESE+ pinout, MAX964ESE+ application, or MAX964ESE+ equivalent, key selection criteria include propagation delay skew (<0.3ns between channels), TTL/CMOS-compatible outputs, 16-pin narrow SO package, and guaranteed rail-to-rail output swing within 0.52V of GND/VCC.
Technical Context
The MAX964ESE+ implements a current-driven output stage enabling rapid slew rates and low static power after transition. Its internal 3.5mV hysteresis eliminates need for external feedback resistors while preventing oscillation near trip points.
It integrates a dedicated SHDN input that places all four comparators into high-impedance state with 270μA total supply current; latch-enable functionality is absent (confirmed by selector guide and pin description - only MAX961/MAX963 support LE).
Key Specifications

Pinout & Package
The MAX964ESE+ is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant and lead-free, with standard 0.150" body width and 0.050" pitch.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA− | Comparator A inverting input - differential pair node accepting Beyond-the-Rails voltage |
| 2 | INA+ | Comparator A noninverting input - referenced against INA− for threshold detection |
| 3 | N.C. | No connection - internally unconnected; tie to GND to prevent parasitic coupling |
| 4 | GND | Analog/digital ground reference - must be low-inductance plane for high-speed stability |
| 5 | INB− | Comparator B inverting input - independent channel with same input specs as INA− |
| 6 | INB+ | Comparator B noninverting input - supports independent dual-threshold sensing |
| 7 | INC− | Comparator C inverting input - third fully differential input pair |
| 8 | INC+ | Comparator C noninverting input - enables triple parallel comparison |
| 9 | IND− | Comparator D inverting input - fourth independent channel |
| 10 | IND+ | Comparator D noninverting input - completes quad-channel architecture |
| 11 | QC | Comparator C TTL output - active-high, rail-swinging, CMOS-compatible |
| 12 | QD | Comparator D TTL output - matches QA/QB electrical behavior and drive strength |
| 13 | VCC | Positive supply input - must be bypassed with 0.1μF ceramic capacitor near pin |
| 14 | SHDN | Shutdown control input - logic-high disables all comparators and forces outputs high-Z |
| 15 | QB | Comparator B TTL output - identical timing and voltage specs to QA/QC/QD |
| 16 | QA | Comparator A TTL output - primary output with 4.5ns tPD and <0.3ns skew vs. other channels |

Use Value: Internal 3.5mV hysteresis prevents false triggering from sensor noise, eliminating need for external Schmitt-trigger components. |
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 |
|---|---|---|---|
| LM393AQDRQ1 | Slower (1.3µs propagation delay), no shutdown, no Beyond-the-Rails input, open-collector outputs | Suitable for low-speed automotive threshold detection only - not viable for GPS or sampling | Select only if cost sensitivity outweighs speed, rail-to-rail output, and low-power requirements |
| ADCMP604BRMZ | Faster (2.8ns), single-channel, no shutdown, 3.3V-only supply, different pinout and package (8-lead MSOP) | Requires four separate devices and additional layout area - increases BOM count and routing complexity | Choose when absolute minimum propagation delay is mandatory and board space permits discrete channel replication |
Compared with LM393AQDRQ1 and ADCMP604BRMZ, the MAX964ESE+ uniquely delivers quad-channel integration, 4.5ns speed, shutdown capability, and Beyond-the-Rails operation in a single 16-pin SO package - reducing system component count and PCB footprint while maintaining industrial temperature range and TTL compatibility.

FAQ
What is the maximum operating supply voltage for the MAX964ESE+?
The MAX964ESE+ supports a supply voltage range of +2.7V to +5.5V. Absolute maximum rating is +6V on VCC relative to GND. Operation above +5.5V violates specifications and risks permanent damage. All electrical characteristics in the datasheet - including propagation delay, output swing, and hysteresis - are guaranteed only within the 2.7V–5.5V range. The MAX964ESE+ is designed for robust +3V and +5V single-supply systems, not higher-voltage rails.
Does the MAX964ESE+ support latch-enable functionality?
No, the MAX964ESE+ does not include latch-enable functionality. According to the official selector guide and pin description table, latch-enable (LE) is supported only on MAX961 and MAX963 variants. The MAX964ESE+ pinout shows no LE pin; pins 1–10 are dedicated to inputs (INA± through IND±), pin 14 is SHDN, and outputs occupy pins 11, 12, 15, and 16. The MAX964ESE+ is a pure quad comparator with shutdown - no latching or transparent latch modes are implemented or electrically supported.
What is the input common-mode voltage range specification for the MAX964ESE+?
The MAX964ESE+ has an input common-mode voltage range of –0.1V to VCC + 0.1V, confirmed in the Electrical Characteristics table under "Input Common-Mode Voltage Range (VCMR)". This Beyond-the-Rails™ capability allows either input to be driven 100mV below GND or 100mV above VCC without false output inversion, provided the other input remains within this range. This feature is critical for interfacing with AC-coupled or floating sources and eliminates need for external level-shifting circuitry in many applications.
Can the MAX964ESE+ drive standard TTL and CMOS logic directly?
Yes, the MAX964ESE+ provides TTL/CMOS-compatible outputs as stated in the Features list and verified in the Electrical Characteristics table. Each output can source or sink 4mA while maintaining VOH ≥ VCC – 0.52V and VOL ≤ 0.52V - meeting standard TTL VOH (≥2.4V at VCC = 5V) and VOL (≤0.4V) requirements, and exceeding typical CMOS VIH/VIL thresholds. No external pull-up resistors or level translators are needed to interface with 74HC, 74AHC, or similar logic families.
What is the propagation delay skew between channels in the MAX964ESE+?
The MAX964ESE+ guarantees propagation-delay skew of ≤0.3ns between any two channels or outputs, as specified in the Electrical Characteristics table under "Propagation-Delay Skew (tSKEW)". This tight matching ensures synchronized decision timing across all four comparators - essential for time-critical applications like multi-phase zero-crossing detection or parallel threshold evaluation in high-speed data acquisition. The value is measured between tPD− and tPD+ and applies across the full –40°C to +85°C temperature range.
