General Description
Not recommended for new designs. Please use HV20220 for
all new designs.
This device is an 8-channel high-voltage analog switch inte-
grated 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 (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.
This IC is suitable for various combinations of high voltage
supplies, e.g., for HV2216 +40V/-120V, or +80V/-80V or +150V/
-10V.

* Absolute Maximum Ratings are those values beyond which damage to the
device may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect
device reliability.
