General Description
The Supertex HV2301 is a low charge injection, 8-channel,
high voltage analog switch integrated circuit (IC) with bleed
resistors. The device can be used in applications requiring high
voltage switching, controlled by low voltage control signals,
such as medical ultrasound imaging, piezoelectric transducer
driver, and printers. The built-in bleed resistors eliminate
voltage built up on capacitive loads such as piezoelectric
transducers. The HV2301 is an enhanced version of the
HV232.
Input data is shifted into an 8-bit shift register that can then
be retained in an 8-bit latch. To reduce any possible clock
feed-through noise, the latch enable bar should be left high
until all bits are clocked in. Data is clocked in during the rising
edge of the clock. Using HVCMOS technology, this device
combines high voltage bilateral DMOS switches and low
power CMOS logic to provide efficient control of high voltage
analog signals.
The device is suitable for various combinations of high
voltage supplies, e.g., V

: +40V/-160V, +100V/-100V,
and +160V/-40V.

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. All voltages are
referenced to device ground.

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