General Description
The Supertex HV20822 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 applications 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, DIN1 and DIN2. A logic high on DIN1 will turn
On switches 0 to 7 and a logic high on DIN2 will turn On
switches 8 to 15.

Absolute Maximum Ratings are those values beyond 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. All voltages are referenced to device ground.
