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 35K
.
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 Y
X
to SW
X
. A logic low connects Y
X
to SW
X
. A logic
hi in CL resets all switches to SW
X
simultaneously.
