74F257A Quad 2-Input Multiplexer with 3-STATE Outputs
General Description
The 74F257A is a quad 2-input multiplexer with 3-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
s Multiplexer expansion by tying outputs together s Non-inverting 3-STATE outputs s Input clamp diodes limit high-speed termination ...
