PCA9548ADBR Information

Description

The PCA9548ADBR is an 8-channel I2C/SMBus switch with reset and voltage translation, designed by Texas Instruments. It's a bidirectional translating switch that allows for voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V buses. The device features active-low reset input, three hardware address pins, and supports hot insertion. It operates with a power-supply voltage range of 2.3 V to 5.5 V and has low standby current. The PCA9548ADBR is commonly used in applications requiring multi-channel I2C bus switching, such as data acquisition systems, test equipment, industrial automation, and communication systems.

Features

According to the product information, the PCA9548ADBR features:

1-of-8 Bidirectional Translating Switches
I2C Bus and SMBus Compatible
Active-Low Reset Input
Three Hardware Address Pins for Use of up to Eight PCA9548A Devices on the I2C Bus
Channel Selection Via I2C Bus
Power-Up with All Switch Channels Deselected
Low RON Switches
Allows Voltage-Level Translation Between 1.8-V, 2.5-V, 3.3-V, and 5-V Buses
No Glitch on Power Up
