These devices are designed for applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging and other piezoelectric transducer drivers. The HV2705 has integrated bleed resistors which eliminate voltage build-up on capacitive loads such as piezoelectric transducers. These ICs shift input data into a 16-bit Shift register that can then be retained in a 16-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. This device bines high-voltage, bilateral DMOS switches and low-power CMOS logic to provide efficient control of high-voltage analog signals. The device is suitable for various binations of highvoltage supplies, e.g., VPP/VNN: +40V/- 160V, +100V/- 100V and +160V/- 40V.
