MAX978 - Low-Power Comparators

This page provides the datasheet information for the MAX978, a member of the MAX976 Low-Power Comparators family.

Description

The MAX976/MAX978/MAX998 dual/quad/single, highspeed, low-power comparators are optimized for +3V/+5V single-supply applications.

They achieve a 20ns propagation delay while consuming only 225µA supply current per comparator.

Features

  • a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA. The MAX976/MAX978/MAX998 inputs have a commonmode voltage range that extends 200mV below ground. Their 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 clea.
