54F 74F258A
Quad 2-Input Multiplexer with TRI-STATE Outputs
General Description
The ’F258A 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 present
the selected data in the complement (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
Y Multiplexer expansion by tying outputs together
Y Inverting TRI-STATE outputs
Y Guaranteed 4000V minimum ESD protection
