The ABLIC Inc. HDL6M06531B is low charge injection 32-channel high-voltage analog switch IC operated only by a single 5V for ultrasound imaging applications.
The HDL6M06531B consists of single-pole, double-throw (SPDT) analog switches controlled by Serial Digital Interface (SDI).
The HDL6M06531B does not require any high-voltage power supply and has a unique pin-out for easy PCB traces.
