MP4816 16-Channel, High-Voltage Analog Switch DESCRIPTION The MP4816 is a 16-channel, high-voltage, single-pole, single-throw, SPST, analog switch designed for medical ultrasound imaging applications. The MP4816 is designed to multiplex transmit and receive voltages to and from multiple piezoelectric transducers (PZT). The output switches are controlled by a 16-bit serial shift register followed by a 16-bit data latch. A data out pin (DOUT) is provided to allow for multiple devices to be cascaded together. This helps minimize the number of input/output (I/O) control lines. A logic high in the data latch turns on the corresponding analog switch. A logic low turns off the corresponding analog switch. The MP4816 does not require any high-voltage supplies.
