PCF8575C - Remote 16-Bit I2C AND SMBus Low-Power I/O Expander

Description

This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 4.5-V to 5.5-V VCC operation.

The PCF8575C provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface serial clock (SCL) and serial data (SDA).

Features

  • 1 I2C to Parallel-Port Expander.
  • Open-Drain Interrupt Output.
  • Low Standby-Current Consumption of 10 μA Maximum.
  • Compatible With Most Microcontrollers.
  • 400-kHz Fast I2C Bus.
  • Address by Three Hardware Address Pins for Use of up to Eight Devices.
  • Latched Outputs With High-Current Drive Capability for Directly Driving LEDs.
  • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II.
  • ESD Protection Exceeds JESD 22.
