PCA9548A Datasheet 8-channel I2c Switch

Manufacturer: NXP Semiconductors

Overview: PCA9548A 8-channel I2C switch with reset Rev. 01 — 15 April 2005 Product data sheet 1.

General Description

The PCA9548A is an octal bi-directional translating switch controlled via the I2C-bus.

The SCL/SDA upstream pair fans out to eight downstream pairs, or channels.

Any individual SCx/SDx channel or bination of channels can be selected, determined by the contents of the programmable control register.
