NXP PCA9554PW

8I²C，SMBusPOR2.3V ~ 5.5V-40°C ~ 85°C

Overview

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)].

The PCA9554PW and PCA9554A are identical except for their fixed I2C address. This allows for up to 16 of these devices (eight of each) on the same I2C/SMBus.
