Supertex inc. HV2221 Low Charge Injection, 8-Channel, Unipolar, Negative High Voltage, Analog Switch Features General Description ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► ►► The Supertex HV2221 is a low charge injection, 8-channel, unipolar, negative high voltage, analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as NDT ultrasound flaw detection, medical ultrasound imaging, piezoelectric transducer drivers, and printers. Low on-resistance, 14Ω max. HVCMOS technology for high performance 3.3 or 5.0V CMOS input logic level 20MHz data shift clock frequency Very low quiescent power dissipation (-10µA) Low parasitic capacitance DC to 50MHz small signal frequency response -60dB typical off-isolation at 5MHz CMOS logic circuitry for low power Excellent noise immunity Cascadable serial data register with latches Flexible operating supply voltages Applications ►► ►► ►► ►► ►► Data is input into an 8-bit shift register that can then be retained in an 8-bit latch. To reduce any possible clock feedthrough noise, the latch enable bar should be left high until all bits are clocked in. Data is clocked in during the rising edge of the clock. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals.

The eight switches operate independently. 2. Serial data is clocked in on the L to H transition of the CLK. 3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flow through the latch. 4. DOUT is high when data in the shift register 7 is high. 5. Shift register clocking has no effect on the switch states if LE is high. 6. The CLR clear input overrides all other inputs.
