MP4865AGBD-T

MP4865A is a 64-channel, high-voltage, single-pole single-throw (SPST) analogue switch with integrated output bleed resistors. The device can multiplex the transmit and receive voltages to and from multiple piezoelectric transducers (PZTs), and is designed for medical ultrasound imaging applications. The output switches are controlled by a 64bit serial shift register, followed by a 64bit data latch. The data out pin (DOUT) allows for multiple devices to be cascaded together. This helps to minimize the number of input/output (I/O) control lines. When the data latch is logic high, the corresponding analogue switch turns on, when the data latch is low, the corresponding switch turns off. The MP4865A does not require any high-voltage supplies. It only requires two low-voltage supplies (3.3V and 5V). The analogue switch can block or pass analogue voltages up to ±90V with peak currents up to ±1.8A. Applications include medical ultrasound imaging, non-destructive testing (NDT).
