Dual 4-Input Multiplexer with TRI-STATEÉ Outputs
General Description
The ’F253isa dual 4-input multiplexer with TRI-STATEÉ
outputs.It can select twobitsof data from four sources
using common select inputs.The output maybe individually
switchedtoa high impedance state witha HIGHonthe
respective Output Enable (OE) inputs, allowingthe outputs interface directly withbus oriented systems.
Features Multifunction capability Non-inverting TRI-STATE outputs Guaranteed 4000V minimum ESD protection
