A BCD code applied to the four inputs, A to D, results in a high level at the selected one of 10 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A through C is decoded in octal code at output 0 to 7 if D = “0”. High drive capability is provided at all outputs to enhance dc and dynamic performance in high fan-out applications. The CD4028BMS is supplied in these 16-lead outline pack- ages: Braze Seal DIP H4S Frit Seal DIP H1E Ceramic Flatpack H3X December 1992 File Number 3303 |
