PCA9546ADT TI I2C Multiplexer | 16-SOIC | 4-Channel, 2.3V-5.5V

Product Overview

The PCA9546ADT from Texas Instruments is a 4-channel I2C multiplexer designed for applications requiring multiple I2C buses with the same address. It allows selective connection of one of four downstream I2C buses to the upstream bus, enabling communication with multiple devices sharing the same address. The device operates over a wide supply voltage range of 2.3V to 5.5V and is available in a compact 16-SOIC package.

Detailed Technical Specifications

Key Features

• 4-channel I2C multiplexer with active-low reset input
• Three hardware address pins allow up to 8 devices on the bus
• Pass-through for I2C bus voltages up to VCC
• Low standby current consumption
• Supports standard (100 kHz) and fast (400 kHz) I2C modes
• Power-on reset ensures all channels deselected
• No glitch on power-up

Target Applications
