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 FCT157T has a common, active-low, enable input. When the 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.
