General Description
The Supertex HV2705 and HV2706 are low charge injection,
16-channel, high voltage analog switch integrated circuits (ICs) with
bleed resistors. The devices can be used in applications requiring
high voltage switching controlled by low voltage control signals, such
as medical ultrasound imaging and piezoelectric transducer drivers.
The bleed resistors eliminate voltage build-up on capacitive loads
such as piezoelectric transducers. The HV2706 has a different pin
configuration than the HV2705.
Input data are shifted into a 16-bit shift register that can then be
retained in a 16-bit latch. To reduce any possible clock feed-through
noise, the latch enable bar 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.
