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
I
Multiplexer expansion by tying outputs together
I
Non-inverting 3-STATE outputs
I
Input clamp diodes limit high-speed termination effects
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
