The ABLIC Inc. HDL6M06522BN is low charge injection 32-channel high-voltage analog switch IC operated only by a single 5V for ultrasound imaging applications.
The HDL6M06522BN consists of single-pole, single-throw (SPST) analog switches controlled by Serial Digital Interface (SDI).
The HDL6M06522BN does not require any high-voltage power supply and has a unique pin-out for easy PCB traces.
