HV2601 / HV2701 Low-Charge Injection, 16-Channel, High-Voltage Analog Switch Features Description High-Voltage CMOS technology for high perfor- HV2601/HV2701 are low-charge injection, 16-channel, mance high-voltage analog switch integrated circuits (ICs). 16-channel high voltage analog switch These devices are designed for use in applications 3.3V input logic level compatible requiring high-voltage switching controlled by low-volt- age control signals, such as medical ultrasound imag- 20 MHz data shift clock frequency ing and other piezoelectric transducer drivers. HV2701 Very low quiescent power dissipation (-10 A) has integrated bleed resistors which eliminate voltage Low parasitic capacitance build-up on capacitive loads such as piezoelectric DC to 50 MHz small signal frequency response transducers. -60dB typical OFF-isolation at 5.0 MHz These ICs shift input data into a 16-bit shift register that CMOS logic circuitry for low power can then be retained in a 16-bit latch. To reduce any Excellent noise immunity possible clock feed-through noise, the latch enable bar Cascadable serial data register with latches should be left high until all bits are clocked in. Data is Flexible operating supply voltages clocked in during the rising edge of the clock. Using Integrated bleed resistors on the outputs High-Voltage CMOS technology, this device combines (HV2701 only) high-voltage, bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. Applications Medical ultrasound imaging The device is suitable for various combinations of high NDT metal flaw detection voltage supplies, e.g., V /V : +40V/-160V, +100V/- PP NN 100V, and +160V/-40V.
