Hi Sir,

Our customer want to use the SN74LVC2G17DCKR or SN74LVC2G17-EP on RS232 (Baudrate：115200) application,

Any risk for this application? or do you have other device can be share for me?

These devices support a rate of 0.1 Mbps just fine.

But RS-232 is an electrical specification whose voltages exceed what logic gates can handle; if you indeed have an RS-232 interface (and not just a UART), you should use some RS-232 transceiver.

Hey Hugo,

You aren't giving me a lot to go on here. The data rate shouldn't be a problem for our device. As long as you operate the device within spec, you shouldn't face any issues.
