Product details
Overview
The MAX964ESE-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), 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 GPS receivers and high-speed sampling circuits.
For engineers reviewing the MAX964ESE-T datasheet, MAX964ESE-T pinout, MAX964ESE-T application, or MAX964ESE-T equivalent, key selection criteria include guaranteed 4.5ns propagation delay at 5mV overdrive, TTL/CMOS-compatible outputs sinking/sourcing 4mA to within 0.52V of GND/VCC, 16-pin narrow SO package, and shutdown functionality enabling low-power portable system design.
Technical Context
The MAX964ESE-T implements a current-driven output stage enabling rapid slew rates while maintaining VOH/VOL within 0.52V of rails under 4mA load. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points.
It integrates a dedicated SHDN input that places all four comparators into high-impedance shutdown state with 270μA per comparator supply current. Unlike MAX961/MAX963, it lacks latch-enable functionality and complementary outputs - confirming its role as a pure quad comparator without storage or dual-output logic.
Key Specifications

Pinout & Package
The MAX964ESE-T is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant, with 0.15mm lead finish and standard JEDEC MO-153 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | No Connection | Internally unconnected; must be left floating or tied to GND to prevent parasitic coupling. |
| 2 | INA- | Inverting input for Comparator A - accepts differential signals up to 100mV beyond rails. |
| 3 | INA+ | Noninverting input for Comparator A - paired with Pin 2 for first comparator channel. |
| 4 | GND | Analog/digital ground reference - requires low-inductance connection to PCB ground plane. |
| 6 | INB- | Inverting input for Comparator B - electrically isolated from other inputs to minimize crosstalk. |
| 7 | INB+ | Noninverting input for Comparator B - forms second independent comparison channel. |
| 8 | INC- | Inverting input for Comparator C - supports simultaneous multi-threshold monitoring. |
| 9 | INC+ | Noninverting input for Comparator C - enables three-channel parallel decision logic. |
| 10 | IND- | Inverting input for Comparator D - completes quad architecture for full signal conditioning. |
| 11 | IND+ | Noninverting input for Comparator D - allows independent threshold setting per channel. |
| 12 | QB | Output for Comparator B - TTL/CMOS-compatible, capable of 4mA sink/source. |
| 13 | QC | Output for Comparator C - active-high, rail-referenced output with 0.52V headroom. |
| 14 | QD | Output for Comparator D - identical drive strength and voltage compliance as QB/QC. |
| 15 | VCC | Positive supply input - must be decoupled with 0.1μF ceramic capacitor placed adjacent to pin. |
| 16 | SHDN | Active-high shutdown control - pulls all outputs to high-Z and reduces ICC to 270μA per comparator. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX964EEE | Identical electrical specs and pinout; differs only in QSOP-16 package (vs. narrow SO-16 of MAX964ESE-T). | QSOP offers finer pitch (0.635mm vs. 1.27mm) and smaller footprint but requires tighter assembly tolerances. | Select MAX964EEE when board real estate is constrained and automated SMT placement capability exists. |
| LM339AVQPWR | Quad comparator with 300ns propagation delay, no internal hysteresis, no shutdown, wider supply range (2V–36V), open-collector outputs. | Used in low-speed industrial controls where timing precision is secondary to voltage flexibility and cost. | Choose LM339AVQPWR only for non-critical timing applications requiring wide-VCC operation and external hysteresis design. |
Compared with MAX964EEE, the MAX964ESE-T offers identical performance in a more manufacturable narrow SO package; compared with LM339AVQPWR, it delivers >60× faster response, integrated hysteresis, shutdown, and rail-compatible outputs - making it suitable for high-frequency signal conditioning where timing integrity is essential.

FAQ
What is the maximum operating supply voltage for the MAX964ESE-T?
The MAX964ESE-T 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 risks exceeding internal bias limits and may cause parametric shift or reliability degradation. All electrical specifications in the datasheet are validated within the 2.7V–5.5V range, including propagation delay, output drive, and hysteresis stability. The MAX964ESE-T must not be operated continuously at +6V.
Does the MAX964ESE-T have latch-enable functionality like the MAX963?
No, the MAX964ESE-T does not include latch-enable functionality. Pinout documentation confirms absence of LE/LEA/LEB terminals - only SHDN, four input pairs (INA± through IND±), four outputs (QA through QD), VCC, and GND are present. The MAX963 provides latch-enable on Pins 3/5 (LEA/LEB) and complementary outputs, whereas the MAX964ESE-T is a pure quad comparator with single-ended TTL/CMOS outputs. This distinction is explicitly stated in the Selector Guide and Pin Configurations section of the datasheet.
What is the input-referred hysteresis value for the MAX964ESE-T?
The MAX964ESE-T has a fixed internal input-referred hysteresis of 3.5mV, as specified in the Electrical Characteristics table under "Input-Referred Hysteresis". This value is process-trimmed and remains stable across temperature (-40°C to +85°C) and supply voltage (2.7V–5.5V). It is not user-adjustable and eliminates the need for external hysteresis resistors. The 3.5mV hysteresis defines the voltage difference between upper and lower trip points, providing noise immunity without compromising response speed.
Can the MAX964ESE-T drive a 50Ω transmission line directly?
No, the MAX964ESE-T cannot drive a 50Ω transmission line directly. Its output stage is rated for 4mA sink/source into loads that allow VOH ≥ VCC – 0.52V and VOL ≤ 0.52V - corresponding to ~130Ω minimum load at 5V (5V / 4mA = 1250Ω). Driving 50Ω would require >100mA, far exceeding its capability and risking damage. For 50Ω interface, use an external buffer amplifier or line driver IC. The MAX964ESE-T is intended for local logic-level interfacing, not RF or high-speed interconnect.
Is the MAX964ESE-T pin-compatible with the MAX964EEE?
Yes, the MAX964ESE-T is pin-compatible with the MAX964EEE. Both devices share identical 16-pin functional mapping: same IN+/IN- assignments per comparator, identical SHDN, VCC, GND, and output pin locations. The sole difference is package type - narrow SO (ESE) vs. QSOP (EEE) - resulting in different land patterns and mechanical dimensions, but no change to electrical connectivity or signal routing. PCB layout must accommodate the respective package footprints, but netlist and schematic symbols remain interchangeable.
