PCF8574N - Remote 8-Bit I/O Expander

This page provides the datasheet information for the PCF8574N, a member of the PCF8574 Remote 8-Bit I/O Expander family.

Datasheet Summary

Description

This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I2C) is designed for 2.5-V to 6-V VCC operation.

The PCF8574 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)].

Features

  • 1 Low Standby-Current Consumption of 10 μA Max.
  • I2C to Parallel-Port Expander.
  • Open-Drain Interrupt Output.
  • Compatible With Most Microcontrollers.
  • Latched Outputs With High-Current Drive Capability for Directly Driving LEDs.
  • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II 2.
