MP4864A Datasheet | Monolithic Power Systems

DESCRIPTION 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. A data out (DOUT) pin allows multiple devices to be cascaded together. This helps minimize the number of input/output (I/O) control lines. A logic high signal in the data latch turns on the corresponding analog switch; a logic low signal turns off the corresponding analog switch. The MP4864A does not require any high-voltage supplies. It only requires two low-voltage supplies (3.3V and 12V). The analog switch can block or pass analog voltages up to ±90V with peak currents of up to ±2A. The MP4864A is available in a BGA-144 (10mmx10mm) package.
