General Description
Not recommended for new designs. Please use HV202 instead.
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.
This IC is suitable for various combinations of high voltage
supplies, e.g., V

: +50V/–150V, or +100V/–100V.
The specifications for the HV204 and HV206 are identical except
that the pinouts in the 28-lead plastic chip carrier are different.

* 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.
