General Description
The Supertex HV2661 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 driver, and printers.
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., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.

Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability. All
voltages are referenced to device ground.
