74F257A is a quad 2-input multiplexer with 3-state outputs, manufactured by National Semiconductor Corporation (NSC).

The 74F257A is a quad 2-input multiplexer with 3-state outputs, manufactured by National Semiconductor Corporation (NSC). It is part of the 74F family of high-speed TTL logic devices. The 74F257A features four separate 2-input multiplexers, each with a common select input (S) and an output enable input (OE). The device operates with a supply voltage range of 4.5V to 5.5V and is designed for high-speed operation with typical propagation delays of 5.5 ns. The outputs are 3-state, allowing them to be connected directly to a bus or other multiplexed outputs. The 74F257A is available in various package types, including DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit). It is designed for use in high-performance digital systems where fast data selection and multiplexing are required.
