I have a project where I want to interface with a keyboard matrix / scanner (this is a PCB from a consumer electronics device). There's already an implementation that uses some analog muxes for this, but I'd like to change this to an MT8809 8x8 crosspoint switch: https://www.microsemi.com/product-directory/analog-cross-point-switches/4916-mt8809
That is, the MT8809 will be used to connect/disconnect the rows and columns of the matrix scanner to simulate keypresses.
The MT8809 runs at 4.5-12v, so I'd connect it to a 5v rail, but the device I'm interfacing to runs at about 3v. Are there any concerns here? Do I need to clip the voltage?
