I am looking for a SPDT mux that can switch between 25V and 46V in less than 300ns.
I saw this device, and I wonder if I can work with it with 46V - knowing that 48V is the absolute maximum.
The 46V is the bias for an Avalanche Photo diode to have X10 gain.
The 25V is to reduce the gain to avoid it to saturates from near back scattered light.
The switching time from 25V to 46V should be less than 300ns.
The APD capacitance is 1.5p.
