74HC251D Description

Short technical summary and product information.

The NXP Semiconductors 74HC251D is an 8-bit multiplexer designed for digital logic applications. It features eight binary inputs (I0 to I7), three select inputs (S0 to S2), and an output enable input (OE). The select inputs allow one of the eight binary inputs to be routed to the complementary outputs (Y and Y).

 

This multiplexer operates within a voltage range of 2V to 6V, with a typical operating voltage of 5V. It offers a propagation delay of 51ns, making it suitable for moderate-speed digital circuits. The device has a maximum supply current of 50mA and provides specific output current capabilities of 5.2mA for high level and 4mA for low level.

 

The 74HC251D is housed in a 16-terminal SOP (Surface Mount) package with a height of 1.45mm. It operates across a wide temperature range from -40°C to 125°C. This component is classified under Universal Bus Functions within the Logic category of Integrated Circuits.
