Part Number : PCA9548APW
Function : 8-channel I2C-bus switch with reset
Package : TSSOP 24 Type
Maker : NXP Semiconductors.
Pinouts : 
Description :
The PCA9548A, PCA9548APW is an octal bidirectional 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 combination of channels can be selected, determined by the contents of the programmable control register.
Features
1. 1-of-8 bidirectional translating switches
2. I2C-bus interface logic; compatible with SMBus standards
3. Active LOW reset input
4. Three address pins allowing up to eight devices on the I2C-bus
5. Channel selection via I2C-bus, in any combination
6. Power-up with all switch channels deselected
