General Description
The Supertex HV208 is a 220V 16-channel high-voltage analog
switch integrated circuit (IC) configured as 2 sets of 8 single pole
single throw analog switches. It is intended for use in applica-
tions requiring high voltage switching controlled by low voltage
control signals such as ultrasound imaging and printers. The 2
sets of 8 analog switches are controlled by 2 input logic controls,
D_IN1 and D_IN2. A logic high on D_IN1 will turn ON switches 0 to 7
and a logic high on D_IN2 will turn ON switches 8 to 15.

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.
