General Description
The Supertex HV2761 is a low charge injection, 24-channel,
high voltage analog switch integrated circuit (IC) intended for
use in applications requiring high voltage switching controlled by
low voltage control signals, such as medical ultrasound imaging,
piezoelectric transducer drivers, and printers. The bleed resistors
eliminate voltage built up on capacitive loads such as piezoelectric
transducers.
Input data is shifted into a 24-bit shift register that can then be
retained in a 24-bit latch. To reduce any possible clock feed through
noise, the latch enable (LE) should be left high until all bits are
clocked in. Data are clocked in during the rising edge of the clock.
Using HVCMOS technology, this device combines high voltage
bilateral DMOS switches and low power CMOS logic to provide
efficient control of high voltage analog signals.
The device is suitable for various combinations of high voltage
supplies, e.g., V
PP
/V
NN
: +40V/-160V, +100V/-100V, and +160V/-40V.
