SN74LV4052A: VCC=3.3V and A & B input high level only reach 1.8V

Hi Sir,

My customer is looking for a pin to pin compatible solution with 74LV4052PW.

And we just found our SN74LV4052A pin define is the same but VCC range can't meet due to my customer is design 74LV4052PW for UART 1.8V interface.

So the VCC, A, B will use 1.8V only but our SN74LV4052A VCC range is 2V to 5.5V only.

And we are just thinking if we can change VCC design to 3.3V and keep A, B input 1.8V for UART high level, is it workable?

Or any other suggestion, please let us know.

Thank you
