PCA95380 - Remote 8-Bit I2C AND SMBus Low-power I/O Expander

Download the PCA95380 datasheet PDF. This datasheet also covers the PCA9538 variant, as both devices belong to the same remote 8-bit i2c and smbus low-power i/o expander family and are provided as variant models within a single manufacturer datasheet.

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), serial data (SDA)].

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.
  • Two Hardware Address Pins Allow up to Four Devices on the I2C/SMBus.
  • Input/Output Configuration Register.
  • Polarity Inversion Register.
  • Power-Up With All Chan.
