Low Charge Injection,

8-Channel, High Voltage Analog Switches

Features

General Description

► HVCMOS^®technology for high performance

► Very low quiescent power dissipation (-10µA)

► Output on-resistance typically 22Ω

► Low parasitic capacitances

This device is a low charge injection, 8-channel, high-voltage

analog switch integrated circuit (IC) intended for use in appli-

cations requiring high voltage switching controlled by low volt-

age control signals, such as ultrasound imaging and printers.

► DC to 50MHz small signal frequency response

► -60dB typical output off isolation at 5.0MHz

► CMOS logic circuitry for low power

► Excellent noise immunity

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

be retained in an 8-bit latch. To reduce any possible clock

feed-through noise, Latch Enable Bar (LE) should be left high

until all bits are clocked in. Using HVCMOS^®technology, this

switch combines high voltage bilateral DMOS switches and

low power CMOS logic to provide efﬁcient control of high volt-

age analog signals.

► On-chip shift register, latch and clear logic circuitry

► Flexible high voltage supplies

Applications

► Medical ultrasound imaging

These ICs are suitable for various combinations of high volt-

age supplies, e.g., V_PP/V_NN: +50V/-150V, or +100V/-100V.

► Piezoelectric transducer drivers
