SCLS224B − DECEMBER 1982 − REVISED SEPTEMBER 2003 description/ordering information (continued) These devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (G) input is at a high logic level.
