HV2301 Low Charge Injection, 8-Channel, High Voltage, Enhanced Analog Switch with Bleed Resistors Features General Description HVCMOS technology for high performance The Supertex HV2301 is a low charge injection, 8-channel, high Integrated bleed resistors on the outputs voltage analog switch integrated circuit (IC) with bleed resistors. 8 Channels of high voltage analog switch The device can be used in applications requiring high voltage 3.3 or 5.0V CMOS input logic level switching, controlled by low voltage control signals, such as 20MHz data shift clock frequency medical ultrasound imaging, piezoelectric transducer driver, and Very low quiescent power dissipation (-10A) printers. The built-in bleed resistors eliminate voltage built up on Low parasitic capacitance capacitive loads such as piezoelectric transducers. The HV2301 DC to 50MHz analog signal frequency is an enhanced version of the HV232. -60dB typical off-isolation at 5MHz CMOS logic circuitry for low power Input data is shifted into an 8-bit shift register that can then be Excellent noise immunity retained in an 8-bit latch. To reduce any possible clock feed- Cascadable serial data register with latches through noise, the latch enable bar should be left high until all Flexible operating supply voltages 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 Applications provide efficient control of high voltage analog signals. Medical ultrasound imaging NDT metal flaw detection The device is suitable for various combinations of high voltage Piezoelectric transducer drivers supplies, e.g., V /V : +40V/-160V, +100V/-100V, and +160V/- PP NN Inkjet printer heads 40V.
