General Description
This device is a low charge injection 8-channel high-voltage
analog switch integrated circuit (IC) intended for use in applica-
tions 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 feed-
through 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. The HV203 has the same electrical specifications as the
HV202, but it is packaged in the 28 lead plastic chip carrier with
the pin configuration of the Supertex HV2216PJ.
This IC is suitable for various combinations of high voltage
supplies, e.g., V
PP/VNN : +50V/–150V, or +100V/–100V.
