PCA6107 - Remote 8-Bit I2C and SMBus Low-power I/O Expander

General Description

This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation.

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

Key Features

  • 1 Low Standby Current Consumption of 1 μA Max.
  • I2C to Parallel Port Expander.
  • Open-Drain Active-Low Interrupt Output.
  • Active-Low Reset Input.
  • Operating Power-Supply Voltage Range of 2.3 V to 5.5 V.
  • 5-V Tolerant I/O Ports.
  • 400-kHz Fast I2C Bus.
  • Three Hardware Address Pins Allow for Use of up to Eight Devices on the I2C/SMBus.
  • Input/Output Configuration Register.
  • Polarity Inversion Register.
  • Internal.
