HV2221

Low Charge Injection, 8-Channel,

Unipolar, Negative High Voltage, Analog Switch

Features

► Low on-resistance, 14Ω max.

► HVCMOS technology for high performance

► 3.3 or 5.0V CMOS input logic level

► 20MHz data shift clock frequency

► Very low quiescent power dissipation - 10µA

► Low parasitic capacitance

General Description

TheSupertexHV2221isalowchargeinjection,8-channel,unipolar,

negativehighvoltage, analogswitchintegratedcircuit(IC)intended

for use in applications requiring high voltage switching controlled

by low voltage control signals, such as NDT ultrasound ﬂaw

detection, medical ultrasound imaging, piezoelectric transducer

drivers, and printers.

► DC to 10MHz analog signal frequency

► -60dB typical off-isolation at 5MHz

► CMOS logic circuitry for low power

► Excellent noise immunity

► Cascadable serial data register with latches

► Flexible operating supply voltages

Data is input 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.

Applications

► NDT metal ﬂaw detection

► Medical ultrasound imaging

► Piezoelectric transducer drivers

► Inkjet printer heads

► Optical MEMS modules
