The MC74HC4053ADWR2G is an analog multiplexer/demultiplexer IC manufactured by ON Semiconductor. It is composed of two independent 1-of-4 multiplexers/demultiplexers with common select and enable inputs, making it useful for selecting one of four analog signals. It runs on a wide range of supply voltages from 2V to 6V, and has an operating temperature range of -55°C to 125°C. The high speed outputs of the IC can be used for both analog signals and digital logic signals. The demultiplexer part of the IC contains two 4-bit latch-type storage registers which can be used to store selected signals. The device also features low power consumption and high noise immunity.
