The HCC/HCF4028B types are BCD-to-decimal or binary-to-octal decoders consisting of buffering on all 4 inputs, decoding-logic gates, and 10 output buffers. 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.

TYPICAL APPLICATIONS The circuit shown in fig. 1 converts any 4-bit code to a decimal or hexadecimal code Fig 2 shows a number of codes and the decimal or hexadecimal number in these codes which must be applied to the input pins of the HCC/HCF4028B to select a particu- lar output. For example : in order to get a ”high” on output n8 the input must be either an 8 expressed in 4-bit binary code, a 15 expressed in 4-bit gray code, or a 5 expressed in excess-3code.
