The MC74HC4051ADR2G from ON Semiconductor is a multiplexer switch integrated circuit (IC), offering two-, three-, four-, and six-input analog multiplexer/demultiplexer logic functions. It is designed to support up to six input single-ended signals and output a single-ended signal. Operating over a temperature range of -55°C to +125°C, the device features a single VDD supply voltage range from 2.0 to 6.0V. It features low ON-state resistance and logic gate-to-output drive capability. Other features include improved switching time, low noise, and excellent signal-to-noise of the selected channel. The device is pin-compatible with the Danieli HC4051A.
