UA9636A: RS232 & UART switching application

Part Number: UA9636A
Other Parts Discussed in Thread: SN74LVC1G3157, , MUX509

Hello,

I used TI's SN74LVC1G3157 analog switch for previous application, but VCC range of this device is not enough for RS232 line.

I'd like to switch RS232 (+12.0V) and UART (+3.0V) signals, and find uA9636A.

Is there any application for switching RS232, UART output from common input?

Switching by input is performed manually in the AP.

thanks,

TS
