* All voltages are referenced to ground. Absolute maximum ratings are those values
which damage to the device may occur. Functional operation under these
conditions is not implied. Continuous operation of the device at the absolute rating
level may affect device reliability.

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.
