Download the PI4MSD5V9545C datasheet PDF. This datasheet also covers the PI4MSD5V9545B variant, as both devices belong to the same 4 channel i2c bus switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The PI4MSD5V9545B is a quad 1-of-4 bidirectional translating switch, controlled via the I2C bus.

The SCL/SDA upstream pair fans out to four SCx/SDx downstream pairs, or channels.

Low standby current Low Ron switches Channel selection via I2C bus
