Product Overview

The LM393P is a dual differential comparator in 8 pin DIP package. This device consists of two independent voltage comparators that are designed to operate from single power supply over wide range of voltages. LM393P can operate with dual power supply as long as difference between two supplies is 2V to 36V and VCC is at least 1.5V more positive than input common mode voltage. Current drain is independent of supply voltage and outputs can be connected to other open collector outputs to achieve wired AND relationships.
  • Wide supply voltage range from 2V to 36V
  • Low drain supply current is typically 0.4mA (independent of supply voltage)
  • Response time of 0.3µs (TTL level input step)
  • Low input bias current is -25nA
  • Low input offset voltage is 2mV
  • Common mode input voltage range includes ground
  • Differential input voltage range equal to maximum rated supply voltage of ±36 V
  • Low output saturation voltage
  • Output compatible with TTL, MOS and CMOS
  • Operating temperature range from 0°C to 70°C
