Microchip Technology HV2621
The HV2621/HV2721/HV2722 devices are 300V, low-charge injection, 16-channel, high-voltage analog switches. These devices are designed for use in applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging, piezoelectric transducer drivers. The HV2721 has integrated bleed resistors on both sides of the switches.| Part No. | HV2621 |

GENERAL DESCRIPTION
HV2621/HV2721 are almost identical to HV2601/2701 but have larger signal range. If the VPP/VNN = ±150V, HV2621/HV2721/HV2722 can pass the analog signal up to ±135V. HV2722 has integrated bleed resistors on one side, SWxA only. HV2621 has no bleed resistors. The bleed resistor eliminates voltage build-up on capacitive loads such as piezoelectric transducers.
