Overview
The TPW3257 device is a high-bandwidth bus switch utilizing a charge pump to provide low and flat on-state resistance.
The TPW3257 can be used to multiplex and de-multiplex up to 4 channels simultaneously in a 2:1 configuration. The OE and S pins are used to control the chip by the bus controller.
The device has isolation during power-off even when the signal exits the switch pins.
The VCC operating range is from 2.3 V to 3.6 V and the switch pins support 0-V to 5-V signal levels.
