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 timing discrimination is critical.
For engineers reviewing the MAX964EEE-T datasheet, MAX964EEE-T pinout, MAX964EEE-T application, or MAX964EEE-T equivalent, key selection considerations include its 16-pin QSOP package, quad-channel architecture without complementary outputs or latch-enable, shutdown control via SHDN pin, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX964EEE-T implements a current-driven output stage enabling TTL/CMOS-compatible outputs that sink or source 4mA while maintaining VOH ≥ VCC–0.52V and VOL ≤ 0.52V. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points.
It supports shutdown mode via a dedicated SHDN pin (active-high), reducing supply current to 270μA per comparator and placing outputs in high-impedance state. Propagation delay skew between channels is limited to 0.3ns, ensuring tight timing alignment across all four comparators.
Key Specifications

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, open-collector outputs requiring pull-ups | Suitable for low-speed industrial monitoring but cannot replace MAX964EEE-T in GPS or line-receiver timing-critical roles | Select only if speed <100kHz and board space allows external hysteresis/pull-up components |
| ADCMP572BCPZ-REEL7 | Faster (2.5ns delay), ECL-compatible outputs, requires negative supply (–5.2V), no shutdown mode | Used in RF test equipment; incompatible with single-supply +3V/+5V systems and power-gated designs | Choose only for ultra-low-jitter applications with dual-supply infrastructure and no power management requirements |
Compared with LM339AQDRQ1 and ADCMP572BCPZ-REEL7, the MAX964EEE-T uniquely combines sub-5ns speed, single-supply operation, integrated hysteresis, and shutdown capability in a space-efficient QSOP - making it irreplaceable in portable high-speed sensing and communications systems.

FAQ
What is the operating temperature range for MAX964EEE-T?
The MAX964EEE-T is specified for operation from –40°C to +85°C. This E-grade rating applies to all MAX964EEE variants and ensures reliable performance in industrial and automotive under-hood environments where thermal stability is essential. The device undergoes 100% production testing at +25°C, with full temperature range specifications guaranteed by design characterization.
Does MAX964EEE-T support complementary outputs?
No, the MAX964EEE-T does not provide complementary outputs. Unlike the MAX961 or MAX963, which feature Q/Q̅ pairs per channel, the MAX964EEE-T delivers only true (non-inverted) outputs: QA, QB, QC, and QD. This architecture simplifies routing in applications requiring single-ended logic-level decisions, such as multi-threshold monitoring or parallel zero-crossing detection.
How is shutdown controlled on MAX964EEE-T?
Shutdown on the MAX964EEE-T is controlled by the SHDN pin (Pin 14), which is active-high. When SHDN is driven high, the device enters low-power mode drawing 270μA per comparator and places all outputs in high-impedance state. For normal operation, SHDN must be tied to GND. Exiting shutdown requires SHDN low and LE (latch-enable) low - though note that MAX964EEE-T lacks latch functionality entirely.
What package type is used for MAX964EEE-T?
The MAX964EEE-T uses a 16-pin QSOP (Quarter-Size Outline Package) with 0.025" pitch and 0.154" body width. It is RoHS-compliant (denoted by "+" suffix in package code E16-1) and matches land pattern 90-0167 per Maxim documentation. This package offers higher pin density than SOIC while maintaining surface-mount compatibility and thermal performance suitable for high-speed analog layouts.
Can MAX964EEE-T operate from a 3.3V supply?
Yes, the MAX964EEE-T operates over a supply range of +2.7V to +5.5V, fully supporting 3.3V nominal systems. At VCC = 3.3V, its outputs maintain VOH ≥ 2.78V and VOL ≤ 0.52V while sinking/sourcing 4mA, ensuring robust interfacing with 3.3V CMOS logic families. Propagation delay increases slightly to ~5.0ns (vs. 4.5ns at 5V), remaining well within high-speed design margins.
