Analog Devices Inc./Maxim Integrated MAX967ESA-T

Overview

MAX967ESA-T from Maxim Integrated is a single ultra-high-speed comparator with Beyond-the-Rails™ input range, 4.5ns propagation delay (5mV overdrive), ±3.5mV internal hysteresis, and TTL/CMOS-compatible output capable of sinking/source 4mA to within 0.52V of GND/VCC. It operates from +2.7V to +5.5V and is used in GPS receivers, high-speed sampling circuits, and threshold detection in portable 3V/5V systems.

For engineers reviewing the MAX967ESA-T datasheet, MAX967ESA-T pinout, MAX967ESA-T application, or MAX967ESA-T equivalent, key selection criteria include propagation delay vs. overdrive, input common-mode range beyond rails, supply current (6.5mA typical at 5V), shutdown capability, and compatibility with low-voltage single-supply signal conditioning architectures.

Technical Context

This comparator uses a current-driven output stage enabling rapid slew rate and rail-to-rail output swing without external pull-ups. Its internal hysteresis (3.5mV) eliminates need for external feedback resistors while preventing oscillation near trip points.

The input stage incorporates dual 200Ω series resistors and front-to-back diode clamps, limiting differential input voltage to ≤2.1V and supporting common-mode operation from –0.1V to VCC + 0.1V - verified across –40°C to +85°C.

Key Specifications

Pinout & Package

MAX967ESA-T is housed in an 8-pin SO (Small Outline) package with exposed pad (package code S8-2), footprint compatible with JEDEC MS-012AA. Thermal performance supports continuous operation at TA ≤ +70°C with 471mW dissipation (derated 5.88mW/°C above).

Equivalent & Alternatives

The following parts are listed as comparable options for similar comparator applications.

Compared with MAX967ESA-T, MAX997ESA offers identical speed and power but omits latch-enable, simplifying design where storage isn't needed; TLV3501CD provides comparable speed but lacks rail-exceeding input range, limiting its use in GPS or line-receiver applications requiring robust common-mode tolerance.

FAQ

What is the maximum operating temperature range for MAX967ESA-T?

The MAX967ESA-T is rated for operation from –40°C to +85°C (E grade). This industrial temperature range is validated across all electrical specifications including propagation delay, input offset voltage, and supply current. The device's thermal derating curve supports continuous operation up to +70°C ambient before power dissipation must be reduced at 5.88mW/°C - consistent with its 8-pin SO package construction.

Does MAX967ESA-T support shutdown mode, and what is its current draw in that state?

Yes, MAX967ESA-T supports active-high shutdown via the SHDN pin (Pin 6). When SHDN is driven high, the device enters low-power mode drawing only 270μA per comparator - a 96% reduction from its normal 6.5mA supply current. During shutdown, the output enters high-impedance state, and the internal bias circuitry is disabled to minimize leakage. Exit from shutdown requires SHDN low and latch-enable (LE) low to ensure deterministic output behavior.

What is the input common-mode voltage range specification for MAX967ESA-T?

The MAX967ESA-T features a Beyond-the-Rails™ input common-mode range of –0.1V to VCC + 0.1V. This means either input (IN+ or IN−) can be driven 100mV below GND or 100mV above VCC without causing false output inversion or damage - provided the other input remains within this same range. This capability is confirmed across the full –40°C to +85°C temperature range and enables direct interfacing with sensors or transducers operating outside the supply domain.

Can MAX967ESA-T drive standard TTL or CMOS logic loads directly?

Yes, MAX967ESA-T provides TTL/CMOS-compatible outputs capable of sourcing or sinking 4mA while maintaining VOH ≥ VCC – 0.52V and VOL ≤ 0.52V. This meets standard TTL VOH (≥2.4V at VCC = 5V) and VOL (≤0.4V) requirements, and exceeds typical CMOS VIH/VIL thresholds. No external pull-up or pull-down resistors are required, simplifying interconnect to FPGAs, microcontrollers, and ASICs operating at 3.3V or 5V.

Is there a latch-enable function on MAX967ESA-T, and how does it differ from MAX961/MAX963?

No, MAX967ESA-T does not include a latch-enable (LE) function. Unlike MAX961 and MAX963 - which feature LE pins enabling output storage - MAX967ESA-T is a simplified variant derived from the MAX997 architecture. It retains ultra-fast propagation delay (4.5ns), shutdown capability, and Beyond-the-Rails inputs, but omits latch control and complementary output. This makes MAX967ESA-T ideal for applications requiring pure high-speed comparison without state retention.
