Microchip HV2801K6-G Multiplexer/Demultiplexer, 32, Voltage, 2-of-1, 64-Pin QFN

The Microchip Low charge injection 32-channel high voltage analog switch integrated circuit intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers. Input data are shifted into a 32-bit shift register that can then be retained in a 32-bit latch. To reduce any possible clock feed through noise, the latch enable bar should be left high until all bits are clocked in. Data are clocked in during the rising edge of the clock.

Low parasitic capacitance
DC to 50MHz analogue signal frequency
CMOS logic circuitry for low power
Excellent noise immunity
Cascadable serial data register with latches
Flexible operating supply voltages
