General Description
The HV20822 is a 220V, 16-channel high-voltage
analog switch integrated circuit (IC) configured as two
sets of eight 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 two sets of eight analog switches are controlled by
two 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.
