Supertex inc. HV20220 Low Charge Injection, 8-Channel, High Voltage Analog Switches Features General Description HVCMOS technology for high performance Very low quiescent power dissipation (-10A) Output on-resistance typically 22 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. (R) 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(R) 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.
