I need to connect 4 UART/Serial output from a single MUX, which Mux IC can I use ?
Use a 74LVC257 at the logic interface and add the line driver to the output.
Hi peterjcs23
74LV257 operates at 3.3V so may be it does not fit the design
I'm pretty sure its 5V tolerant on its inputs.
Its tolerant on inputs but VCC max is 3.6v
it is possible to drop the 5V supply to 3.3V...Peter
