Microchip Technology HV2705
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. This device combines high-voltage, bilateral DMOS switches and low-power CMOS logic to provide efficient control of high-voltage analog signals.| Part No. | HV2705 |

DESCRIPTION
The HV2605 and HV2705 are 16-channel low harmonic distortion high-voltage analog switch integrated circuits (ICs). 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. To reduce any possible clock feed-through noise, the latch enable bar should be left high until all bits are clocked in.
