MP4864A Overview
The MP4864A is a 64-channel, high-voltage, single-pole single-throw (SPST) analog switch with integrated output bleed resistors designed for medical ultrasound imaging applications. It is designed to multiplex the transmit and receive voltages to and from multiple piezoelectric transducers (PZTs). The output switches are controlled by a 64-bit serial shift register, followed by a 64-bit data latch.
