General Description
Not recommended for new designs. Please use HV202 instead.
This device is an 8-channel high-voltage integrated circuit (HVIC)
intended for use in applications requiring high voltage switching
controlled by low voltage signals; e.g., ultrasound imaging and
printers. Input data is shifted into an 8-bit shift register which can
then be retained in an 8-bit latch. Using HVCMOS technology, this
HVIC combines high voltage bilateral DMOS switches and low
power CMOS logic to provide efficient control of high voltage
analog signals.

* 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.

Notes:
1. The eight switches operate independently.
2. Serial data is clocked in on the L → H transition CLK.
3. The clear input over rides all other inputs.
4. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flows through the latch.
5. DOUT is high when switch 7 is on.
6. Shift register clocking has no effect on the switch states if LE is H.
