Integrated bleed resistors on outputs (HV2762 only)
Description
HV2662/HV2762 are low-charge injection, 24-channel,
high-voltage analog switch integrated circuits (ICs).
These ICs excel in applications requiring high-voltage
switching controlled by low-voltage control signals such
as medical ultrasound imaging, piezoelectric trans-
ducer driver, and printers. HV2762 provides integrated
bleed resistors that eliminate voltage build-up on
capacitive loads such as piezoelectric transducers.
HV2662 does not have integrated bleed resistors.
HV2662/HV2762 shift input data into a 24-bit shift reg-
ister that can then be retained in a 24-bit latch. To
reduce any possible clock feed through noise, the
latch-enable bar should be left high until all bits are
clocked in during the rising edge of the clock. Using
High Voltage CMOS technology, these ICs combine
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

: +40V/-160V, +100V/-
100V, and +160V/-40V.
