    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. ...
