DESCRIPTION:
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.
enable input is not active, all four outputs are held low. A common application
of FCT157T is to move data from two different groups of registers to a
common bus. Another application is as a function generator. The FCT157T
can generate any four of the 16 different functions of two variables with one
variable common.
The FCT157T is a high-speed quad 2-input multiplexer built using an
