A BCD code applied to the four inputs, A to D, results in a high level at the selected one of decimal decoded outputs. Similarly, a -bit binary code applied to inputs A through C is decoded in octal code at output to if D =. High drive capability is provided at all outputs to enhance dc and dynamic performance in high fan-out applications.
