Part Number: SN74LVC1G3157
Does the 74LVC1G3157G input/output voltage swing need to equal or lower than Vcc(power pin)?
You could refer to the below circuit, we use this case which Vcc and select pin is 3.3V level, and the IO to control the LED with 5V power.
Is there any risk with this configuration?
If there is 5V on the I/O pin (A/B0/B1) of the SN74LVC1G3157 with Vcc =3.3V it will violate the recommended operating conditions of the device.
To support I/O voltages greater than Vcc you will need a device with beyond Vcc feature like the TMUX1072 or TMUX1574 device where the max I/O voltage limit is not referenced to Vcc.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
