Analog Devices Inc./Maxim Integrated MAX964ESE

Overview

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, Beyond-the-Rails™ input range extending 100mV beyond rails, and TTL/CMOS-compatible outputs. It is used in high-speed sampling circuits and GPS receivers where precise timing and rail-to-rail input tolerance are critical.

For engineers reviewing the MAX964ESE datasheet, MAX964ESE pinout, MAX964ESE application, or MAX964ESE equivalent, key selection considerations include propagation delay skew (<0.3ns between channels), shutdown enable functionality, 16-pin narrow SO package footprint, and guaranteed performance across -40°C to +85°C.

Technical Context

The MAX964ESE implements a current-driven output stage enabling fast slew rates and rail-swing capability down to 0.52V from GND or VCC while sourcing/sinking 4mA. 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 quiescent 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

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and high-speed ICs for industrial, communications, and consumer applications.

The MAX961–MAX964 family was engineered specifically for ultra-high-speed, low-power, single-supply comparator applications demanding nanosecond-level timing accuracy and rail-to-rail input flexibility.

FAQ

What is the maximum operating supply voltage for 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 risks permanent damage and violates the guaranteed electrical specifications defined in the datasheet. For reliable long-term use, maintain VCC within the 2.7V–5.5V range specified across the full -40°C to +85°C temperature span.

Does MAX964ESE support true rail-to-rail input operation?

Yes, the MAX964ESE supports Beyond-the-Rails™ input operation: its input common-mode range extends from -0.1V to VCC + 0.1V. This means either input can safely accept voltages 100mV below GND or 100mV above VCC without inversion or damage, provided the other input remains within that same extended range. This capability eliminates level-shifting circuitry in mixed-supply or sensor-biased systems.

Can MAX964ESE outputs drive standard CMOS loads directly?

Yes, MAX964ESE outputs are TTL/CMOS-compatible and can directly drive standard CMOS inputs. Each output sinks or sources up to 4mA while maintaining VOH ≥ VCC − 0.52V and VOL ≤ 0.52V. No external pull-up or pull-down resistors are needed. The output stage is actively driven - unlike open-collector comparators - ensuring fast, deterministic logic transitions without external components.

Is there a latch-enable function on MAX964ESE?

No, the MAX964ESE does not include a latch-enable feature. That functionality is exclusive to the MAX961 and MAX963 variants. The MAX964ESE is a pure quad comparator with shutdown control (SHDN pin) but no latch or complementary outputs. Pin 2 is N.C., and no LE or LEB pins are present - confirmed by the official pin configuration diagram for MAX964 in the datasheet.

What is the propagation delay skew between channels in MAX964ESE?

The MAX964ESE guarantees propagation-delay skew of ≤0.3ns between any two comparators (e.g., tPD of channel A vs. channel B). This tight matching ensures synchronous decision-making across all four channels - critical for time-interleaved sampling, parallel threshold detection, and phase-coherent signal processing in GPS and high-speed test equipment using the MAX964ESE.
