MAX976ESA

The MAX976ESA is a dual, high-speed, low-power comparator optimized for +3V/+5V single-supply applications. It achieves a 20ns propagation delay while consuming only 225µA supply current per comparator. The inputs have a common-mode voltage range that extends 200mV below ground. Its outputs are capable of rail-to-rail operation without external pullup circuitry, making these devices ideal for interface with CMOS/TTL logic. All inputs and outputs can tolerate a continuous short-circuit fault condition to either rail. The comparators' internal hysteresis ensures clean output switching, even with slow-moving input signals.

This comparator is available in a space-saving 8-pin SOIC package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. Key electrical characteristics include a maximum propagation delay of 28ns, a typical supply current of 650µA, and typical hysteresis of 4mV. It also features typical CMRR of 95dB and PSRR of 100dB.

Applications for the MAX976ESA include battery-powered systems, threshold detectors/discriminators, 3V systems, IR receivers, and digital line receivers.
