General Description
Not recommended for new designs. Please use HV20220 for
new designs.
This device is a low charge injection 8-channel high-voltage ana-
log switch integrated circuit (IC) intended for use in applications
requiring high voltage switching controlled by low voltage control
signals, such as ultrasound imaging and printers. 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 feedthrough 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 voltage analog signals.
