54F74F253

Dual 4-Input Multiplexer with TRI-STATE

Outputs

General Description

The ’F253 is a dual 4-input multiplexer with TRI-STATE

outputs It can select two bits of data from four sources

using common select inputs The output may be individually

switched to a high impedance state with a HIGH on the

respective Output Enable (OE) inputs allowing the outputs

to interface directly with bus oriented systems
