Supertex inc. HV2201 Low Charge Injection, 8-Channel, Enhanced, High Voltage Analog Switch Features General Description HVCMOS technology for high performance The Supertex HV2201 is a low charge injection, 8-channel, high 8 Channels of high voltage analog switch voltage analog switch integrated circuit (IC). The device can be 3.3 or 5.0V CMOS input logic level used in applications requiring high voltage switching controlled by 20MHz data shift clock frequency low voltage control signals, such as medical ultrasound imaging, Very low quiescent power dissipation (-10A) piezoelectric transducer drivers, and printers. The HV2201 is an Low parasitic capacitance enhanced version of the HV20220. DC to 50MHz analog signal frequency -60dB typical off-isolation at 5.0MHz Input data is shifted into an 8-bit shift register that can then be CMOS logic circuitry for low power retained in an 8-bit latch. To reduce any possible clock feed- Excellent noise immunity through noise, the latch enable bar should be left high until all Cascadable serial data register with latches bits are clocked in. Data is clocked in during the rising edge of Flexible operating supply voltages 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. Applications Medical ultrasound imaging The device is suitable for various combinations of high voltage NDT metal flaw detection supplies, e.g., V /V : +40V/-160V, +100V/-100V, and +160V/- PP NN Piezoelectric transducer drivers 40V.
