The Texas Instruments PCA9548APWR is an 8-channel bidirectional translating switch compatible with I2C and SMBus protocols. This device facilitates voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V buses, making it versatile for mixed-voltage systems.
Key electrical specifications include an operating supply voltage range of 2.3V to 5.5V and a maximum clock frequency of 400 kHz. It features an active-low reset input and three hardware address pins, allowing up to eight PCA9548A devices on an I2C bus. The switch channels are deselected upon power-up, and it supports hot insertion with no glitch.
Packaged in a 24-TSSOP, the PCA9548APWR is designed for surface mount applications. Its operating temperature range is -40°C to 85°C. The device offers 5-V tolerant inputs and low standby current, contributing to efficient system design.
