General Description

The Supertex HV2301 is a low charge injection, 8-channel, high

voltage analog switch integrated circuit (IC) with bleed resistors.

The device can be used in applications requiring high voltage

switching, controlled by low voltage control signals, such as

medical ultrasound imaging, piezoelectric transducer driver, and

printers. The built-in bleed resistors eliminate voltage built up on

capacitive loads such as piezoelectric transducers. The HV2301

is an enhanced version of the HV232.

Input data is shifted into an 8-bit shift register that can then be

retained in an 8-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 is 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.
