Overview

This 8-bit input/output (I/O) expander for the two-wire bidirectional bus (I2C) is designed to operate at VCC from 2.5V to 6V. The PCF8574A device provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock (SCL), serial data (SDA)]. The device features an 8-bit quasi-bidirectional I/O port (P0–P7), including latched outputs with high-current drive capability for direct LED driving. Each quasi-bidirectional I/O can be used as either an input or output without the need for a data direction control signal. At power-on, these I/Os are set to a high level. In this mode, only one current source connected to VCC is active.

Applications

  • Telecom shelters: filter units
  • Servers
  • Routers (telecom switching equipment)
  • Personal computers
  • Personal electronic products
  • Industrial automation
  • Products with GPIO-constrained processors

Key features

  • Low standby current consumption, 10μA maximum
  • I2C to parallel port expander
  • Open-drain interrupt output
  • Compatible with most microcontrollers
  • Latched outputs with high current drive capability for direct LED driving
  • Latch-up performance exceeds 100mA, compliant with JESD78 Class II specifications
