    8-Channel, High Voltage Analog Switches
    Features General Description ►► HVCMOS technology for high performance
    ►► Very low quiescent power dissipation (-10µA)
    ►► Output on-resistance typically 22Ω
    ►► Low parasitic capacitances
    ►► DC to 50MHz small signal frequency response
    ►► -60dB typical output off isolation at 5.0MHz
    ►► CMOS logic circuitry for low power
    ►► Excellent noise immunity
    ►► On-chip shift register, latch and clear logic circuitry
    ►► 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. ® 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 HVCMOS® technology, this
    switch combines high voltage bilateral DMOS switches and
    low power CMOS logic to provide efficient control of high voltage analog signals. Applications
    ►► Medical ultrasound imaging
    ►► 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
