54F/74F257A

Quad 2-Input Multiplexer with TRI-STATE Outputs

General Description

Features

Multiplexer expansion by tying outputs together

The ’F257A 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 pres-

ent the selected data in true (non-inverted) form. The out-

puts 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.

Non-inverting TRI-STATE outputs

Input clamp diodes limit high-speed termination effects

Guaranteed 4000V minimum ESD protection
