Overview

µPC177, µPC339 comparators are designed for single power supply operation. The features include lowvoltage operation, common-mode input voltage range from V-(GND) level, open-collector output and low current consumption. Furthermore, these products can operate with both power supplies and can be widely used for various voltage comparison application. Depending on the usage and operating ambient temperature range, the μPC177 is design for communication industries and μPC339 is design for general purposes. In addition, compatible DC parameter selection for the comparators are available under special products. Along with this series of lineup, the dual type comparators, μPC277 and 339 with the same circuit configuration are also available.

  • Input Offset Voltage: ±2 mV (TYP.)
  • Input Bias Current: 25 nA (TYP.)
  • Voltage Gain: 1.3 µs (TYP.)
  • Pulse Response Time: 16 mA (TYP.)
  • A wired OR is possible as the output is an open collector
  • Low Voltage Operation: V + - V - : 2 ~ 32 V
