    Supertex inc. HV20220 Low Charge Injection,
    8-Channel, High Voltage Analog Switches
    Features General Description в–єв–є HVCMOS technology for high performance
    в–єв–є Very low quiescent power dissipation (-10ВµA)
    в–єв–є Output on-resistance typically 22О©
    в–єв–є Low parasitic capacitances
    в–єв–є DC to 50MHz small signal frequency response
    в–єв–є -60dB typical output off isolation at 5.0MHz
    в–єв–є CMOS logic circuitry for low power
    в–єв–є Excellent noise immunity
    в–єв–є On-chip shift register, latch and clear logic circuitry
    в–єв–є Flexible high voltage supplies This device is a low charge injection, 8-channel, high-voltage
    analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and printers. В® Input data is shifted into an 8-bit shift register which can then
    be retained in an 8-bit latch. To reduce any possible clock
    feed-through noise, Latch Enable Bar (LE) should be left high
    until all bits are clocked in. Using HVCMOSВ® technology, this
    switch combines high voltage bilateral DMOS switches and
    low power CMOS logic to provide efficient control of high voltage analog signals. Applications
    в–єв–є Medical ultrasound imaging
    в–єв–є Piezoelectric transducer drivers Block Diagram These ICs are suitable for various combinations of high voltage supplies, e.g., VPP/VNN : +50V/-150V, or +100V/-100V. Level Output
