description

These data selectors/multiplexers contain

inverters and drivers to supply full data selection

to the four output gates. A separate strobe (G)

input is provided. A 4-bit word is selected from one

of two sources and is routed to the four outputs.

The ′ALS157A and SN74AS157 present true

data. The ′ALS158 and SN74AS158 present

inverted data to minimize propagation delay time.
