HV214

250V Low Charge Injection

8-Channel High Voltage Analog Switch

Features

General Description

► HVCMOS^®technology for high performance

► Very low quiescent power dissipation -10µA

► Low parasitic capacitances

The Supertex HV214 is a low charge injection 8-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

drivers, inkjet printer heads and optical MEMS modules.

► DC to 10MHz analog signal frequency

► -60dB typical output off isolation at 5MHz

► -60dB typical off-isolation at 5MHz

► CMOS logic circuitry for low power

► Excellent noise immunity

► On-chip shift register, latch and clear logic

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 feedthrough 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 HVCMOS^®

technology, this device combines high voltage bilateral DMOS

switches and low power CMOS logic to provide efﬁcient control of

high voltage analog signals.

circuitry

► Flexible high voltage supplies

► Surface mount packages

The device is suitable for various combinations of high voltage

supplies, e.g., V_PP/V_NN: +40V/-210V, +125V/-125V, +210V/-40V.

Applications

► Medical ultrasound imaging

► Non-destructive evaluation

► Inkjet printer heads

► Optical MEMS modules
