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

/V
NN
: +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.
