PCA9548ADBR Description

Short technical summary and product information.

The PCA9548ADBR from Texas Instruments is a versatile 8-channel bidirectional translating switch that facilitates communication over I2C and SMBus protocols. This device is crucial for systems requiring voltage-level translation between different bus voltages, supporting transitions between 1.8V, 2.5V, 3.3V, and 5V.

 

Key electrical specifications include an operating voltage range of 2.3V to 5.5V and a maximum clock frequency of 400kHz. The switch features an active-low reset input and three hardware address pins, allowing up to eight PCA9548A devices to be used on the same I2C bus. It is designed to prevent glitches during power-up and supports hot insertion.

 

Packaged in a 24-SSOP, the PCA9548ADBR is suitable for surface mount applications. Its operating temperature range is from -40°C to 85°C. The device also offers 5V tolerant inputs and low standby current, making it an efficient choice for complex interface management in embedded systems.
