Description

The  IDT74FCT257AT is a high-speed quad 2-input multiplexer built using an advanced dual metal CMOS technology.  Four bits of data from two sources can be selected using the common select input.  The four buffered outputs present the selected data in the true (non-inverting) form.

The IDT74FCT257AT has a common Output Enable (OE</a>) input.  When OE</a> ishigh, all outputs are switched to a high-impedance state allowing the outputs to interface directly with bus-oriented systems.
