General Description
The 74F257A is a quad 2-input multiplexer with TRI-STATE outputs. Four bits of data from two sources can be selected using a Common Data Select input. The four outputs present the selected data in true (non-inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.

Features
■ Multiplexer expansion by tying outputs together
■ Non-inverting TRI-STATE outputs
■ Input clamp diodes limit high-speed termination effects
■ Guaranteed 4000V minimum ESD protection
