Other Parts Discussed in Thread: TMUX1574, SN3257-Q1
We are using the SN74CB3Q3257 (4 channels ,2:1, Multiplexer) in our application.
The supply voltage is 3.3V, so the Vs must >2V to control. But the Vs voltage from MCU now is 1.8V.
Can we add a trido from 3.3V to enhance the drive voltage?
Or can use Vcc=1.8V when the Vin=1.8V?
In addition, do we have device which selected pin voltage is 1.8V compatible.
Vin=1.8V(SPI up to 32MHz) and Vcc can be 1.8V ,3.3V, 5V
