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 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,

1 and DIN2. A logic high on DIN1 will turn ON switches 0 to 7

D

IN

and a logic high on D

PP

2 will turn ON switches 8 to 15.
