QUAD 2-INPUT
MULTIPLEXER
DESCRIPTION:
The FCT257T is a high-speed quad 2-input multiplexer built using an
advanced dual metal CMOS technology. Four bits of data fromtwo sources
can be selected using the common select input. The four buffered outputs
present the selected data in the true (non-inverting) form
The FCT257T has a common Output Enable (
OE
) input. When
OE
is
high, all outputs are switched to a high-impedance state allowing the outputs
to interface directly with bus-oriented systems.
Three other multiplexers
