应用功能： CD4028BM/CD4028BC is a BCD-to-decimal or binaryto- octal decoder consisting of 4 inputs, decoding logic gates, and 10 output buffers. A BCD code applied to the 4 inputs, A, B, C, and D, results in a high level at the selected 1-of-10 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A, B, and C is decoded in octal at outputs 0±7. A high level signal at the D input inhibits octal decoding and causes outputs 0±7 to go low.
