  HV2802/HV2902
  Low Harmonic Distortion, 32-Channel SPST,
  High-Voltage Analog Switch
  Features General Description 32-Channel SPST (Single-Pole, Single-Throw)
  High-Voltage Analog Switch 3.3V or 5.0V CMOS Input Logic Level 20 MHz Data Shift Clock Frequency High-Voltage CMOS (HVCMOS) Technology for
  High Performance Very Low Quiescent Power Dissipation (10 ВµA) Low Parasitic Capacitance DC to 50 MHz Analog Signal Frequency -60 dB Typical OFF-Isolation at 5.0 MHz CMOS Logic Circuitry for Low Power Excellent Noise Immunity Cascadable Serial Data Register with Latches Flexible Operating Supply Voltages Integrated Bleed Resistors on the Outputs
  (HV2902 only) The HV2802 and HV2902 are low-charge injection,
  32-channel, high-voltage analog switches intended for
  use in applications requiring high-voltage switching
  controlled by low-voltage control signals, such as
  medical ultrasound imaging, driving piezoelectric
  transducers and printers. The HV2902 has integrated
  bleed resistors which eliminate voltage build-up on
  capacitive loads such as piezoelectric transducers. Applications Medical Ultrasound Imaging Non-Destructive Testing (NDT) Metal Flaw
  Detection Piezoelectric Transducer Drivers Inkjet Printer Heads Optical MEMS Modules Input data are shifted into a 32-bit shift register that can
  then be retained in a 32-bit latch. To reduce any
  possible clock feedthrough noise, the latch enable bar
  should be left high until all bits are clocked in. Data are
  clocked in during the rising edge of the clock. Using the
  HVCMOS technology, this device combines
  high-voltage bilateral DMOS switches and low-power
  CMOS logic to provide efficient control of high-voltage
  analog signals. ...
