General Description

Not recommended for new designs. Please use HV202
instead.
This device is an 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 ultra-
sound 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 technol-
ogy, 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 sup-
plies, e.g., for HV2116 +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.
