MAX942CPA - MAX942 Dual Single Supply Comparators

Product Details

The MAX942 is a dual comparator optimized for use on 3V and 5V power supplies. The comparators are high speed, low power devices and will accept rail-to-rail inputs. The device has a propagation time of 80ns and the comparator supply current is 350µA. The MAX942 has internal hysteresis and the input/output pins can tolerate a continuous short-circuit fault to either rail.


Features

  • Optimized for 3V and 5V Applications (operation down to 2.7V)
  • Fast, 80ns Propagation Delay (5mV overdrive)
  • Rail-to-Rail Input Voltage Range
  • Low Power: 1mW Power Dissipation per Comparator(3V) 350µA Supply Current
  • Low, 1mV Offset Voltage
  • Internal Hysteresis for Clean Switching
  • Outputs Swing 200mV of Power Rails
  • CMOS/TTL-Compatible Outputs
