General Description
The Supertex HV207 is an 8-channel high-voltage analog switch
integrated circuit (IC) configured as a dual 1 of 4 analog switch.
The 2 sets of 4 analog switches are controlled independently
with the 2 independent 1:4 decoders. The addressed switches
are turned ON and the unaddressed switches are turned OFF. A
logic high on the input clear pin will turn OFF all output switches
regardless of the address input states.
