General Description

The HV2601/HV2701 devices are low-charge injection,

16-channel, high-voltage analog switch integrated

circuits (ICs). These devices are designed for use in

applications requiring high-voltage switching controlled

by low-voltage control signals, such as medical

ultrasound imaging and other piezoelectric transducer

drivers. The HV2701 has integrated bleed resistors

which eliminate voltage build-up on capacitive loads,

such as piezoelectric transducers.

These ICs shift input data 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

High-Voltage CMOS technology, these devices

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-

+100V/–100V, and +160V/–40V.
