Quad 2-Input Multiplexer with TRI-STATE Outputs
General Description
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
Features
Y Multiplexer expansion by tying outputs together
Y Non-inverting TRI-STATE outputs
Y Input clamp diodes limit high-speed termination effects
Y Guaranteed 4000V minimum ESD protection
