The ABLIC Inc. HDL6V5541 is a four-channel, unconditional five-level, high-voltage, high-speed pulser with active ground damping for medical ultrasound imaging applications. The HDL6V5541 consists of logic interfaces, level translators, MOSFET gate drive buffers employing direct coupling topology, high-voltage, high-current MOSFETs, and active T/R switches. The HDL6V5541 adopts a 3-to-6 decoder with user-selectable clock/transparent mode control.
