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