    Docket ↓
    No High-Voltage Bias, Low Harmonic Distortion,
    32-Channel, High-Voltage Analog Switch
    Features General Description 32-Channel, High-Voltage Analog Switch No High-Voltage Supplies Required 32-Channel, Single-Pole, Single-Throw (SPST)
    Individual Switching or Bank Switching 3.3V CMOS Input Logic Level 66 MHz Data Shift Clock Frequency Silicon-on-Insulator (SOI) High-Voltage
    Technology for High Performance Standby mode for Low-Power Dissipation Low-Parasitic Capacitance DC to 50 MHz Analog Small-Signal Frequency 200 kHz to 50 MHz Large-Signal Frequency -70 dB Typical Off Isolation at 5.0 MHz Excellent Noise Immunity Cascadable Serial Data Register with Latches Integrated Bleed Resistors on the Outputs (both
    sides for HV2903, one side for HV2904) The HV2803/HV2903/HV2904 devices are low harmonic
    distortion, low charge injection, 32-channel, high-voltage
    analog switches without high-voltage supplies. They are
    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. Applications Medical Ultrasound Imaging Non-Destructive Testing (NDT) Metal Flaw
    Detection Piezoelectric Transducer Drivers Inkjet Printer Heads Optical MEMS Modules The HV2903 device has integrated bleed resistors at
    both sides of the switches; the HV2904 device has
    bleed resistors at one side only, while the HV2803
    device has no bleed resistors. The bleed resistor
    eliminates voltage build-up on capacitive loads, such
    as piezoelectric transducers.
    The HV2803/HV2903/HV2904 devices have two
    modes of operation determined by the MODE pin input.
    MODE input high enables an individual Switching
    mode of 32-channel SPST switches and MODE input ...
