General Description

The Supertex HV209 is a 200V low charge injection 12-

channel high voltage analog switch configured as 6 SPDT

analog switch intended for medical ultrasound applications.

Bleed resistors are integrated on the output switches to

eliminate charge built up on the piezo electric transducers.

The bleed resistors are at a nominal value of 35KΩ. Using

HVCMOS technology, this device combines high voltage

bilateral DMOS switches and low power CMOS logic to pro-

vide efficient control of high voltage analog signals. The

outputs are configured as single pole double throw analog

switches. Data is shifted into a 6-bit shift register using an

external clock. The LE latches the shift register data into the

individual switch latches. A logic high connects a switch

common YX to SWX. A logic low connects YX to SWX. A logic

hi in CL resets all switches to SWX simultaneously.
