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 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 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.

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

► Flexible high voltage supplies

► Surface mount packages

Applications

► Medical ultrasound imaging

► Non-destructive evaluation

► Inkjet printer heads

The device is suitable for various combinations of high voltage

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

► Optical MEMS modules
