HV2662/HV2762 Low Harmonic Distortion, 24-Channel SPST High-Voltage Analog Switch Features 24-Channel of High-Voltage Analog Switch 3.3V or 5.0V CMOS Input Logic Level 24-Channel SPST Configuration 20 MHz Data Shift Clock Frequency HVCMOS Technology for High Performance Very Low Quiescent Power Dissipation (~10 µA) Low Parasitic Capacitance DC to 50 MHz Analog Signal Frequency -60 dB Typical OFF-Isolation at 5.0 MHz CMOS Logic Circuitry for Low Power Excellent Noise Immunity Cascadable Serial Data Register with Latches Flexible Operating Supply Voltages Integrated Bleed Resistors on Outputs (HV2762 Only) Applications Medical Ultrasound Imaging Piezoelectric Transducer Drivers Inkjet Printer Heads Optical MEMS Modules General Description HV2662/HV2762 are low-charge injection, low harmonic distortion, 24-channel, high-voltage analog switch integrated circuits (ICs). These ICs excel in applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers. HV2762 provides integrated bleed resistors that eliminate voltage build-up on capacitive loads such as piezoelectric transducers. HV2662 does not have integrated bleed resistors. HV2662/HV2762 shift input data into a 24-bit shift register that can then be retained in a 24-bit latch. To reduce any possible clock feed through noise, the latch-enable bar should be left high until all bits are ...
