PCA9534A - Remote 8-BIT I2C and SMBus Low-Power I/O Expander

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.
  • 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 Up to Eight Devices on the I2C/SMBus.
  • Allows Up to 16 Devices on the I2C/SMBus When Used in Conjunction with the PCA9534 See Device Comparison Table for I2C Expander offering.
