General Description
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.
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.
The device is suitable for various combinations of high voltage
supplies, e.g., V
PP/VNN: +40V/-210V, +125V/-125V, +210V/-40V.
