These devices are designed for use in applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging and other piezoelectric transducer drivers. The HV2701 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. Using High-Voltage CMOS technology, these devices bine 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. 42-Ball Bumped Die (Top View) 7 654 13 12 11 10 18 17 98 15 14 22 21 26 25 20 19 24 23 34 33 32 31 30 29 28 27 42 41 40 39 38 37 36 35 48-Lead LQFP (Top View) 48...
