MP4864AGBD, 64 Circuit IC Switch 1:1 20Ohm 144-BGA (10x10)

MP4864A SPST Analog Switch Monolithic Power Systems (MPS) MP4864A SPST Analog Switch is a 64-channel, high-voltage, single-pole single-throw (SPST) analog switch that includes integrated output bleed resistors intended for medical ultrasound imaging applications. The MP4864A is optimized to multiplex the transmit and receive voltages to and from multiple piezoelectric transducers (PZTs). A 64-bit serial shift register manages the output switches, followed by a 64-bit data latch. A data out (DOUT) pin enables multiple switches to cascade together, minimizing the number of input/output (I/O) control lines. A logic high signal in the data latch turns on the corresponding analog switch, while a logic low signal turns it off.
