These monolithic data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs.
The LSTTL /MSI SN54 /74LS157 is a high speed Quad 2-Input Multiplexer . Four bits of data from two sources can be selected using the common Select and Enable inputs. The four buf fered outputs present the selected data in the true (non-inverted) form. The LS157 can also be used to generate any four of the 16 dif ferent functions of two variables.
