Manufacturer Part Number

PCA9548ADWR

Manufacturer

Texas Instruments

Introduction

The PCA9548ADWR is a 1-of-8 I2C-bus switch/multiplexer that allows a single I2C/SMBus master to communicate with multiple I2C/SMBus slaves. It is designed for use in systems where more than one I2C/SMBus device needs to be accessed by a single master.

Product Features and Performance

Provides eight bidirectional channels

Requires only one address for all eight channels

Low power consumption

On-chip logic control

Individual channel enable/disable

Propagation delay of 35 ns (typical)

Latch-up performance exceeds 100 mA per JESD 78 Class II

ESD protection exceeds 4 kV human body model (HBM) and 1 kV charged device model (CDM) per JESD 22
