CD4028 Pinout Diagram

●The CD4028BE is a MOS BCD-to-Decimal or Binary-to-Octal Decoder/Driver consisting of buffering on all 4 inputs, decoding-logic gates and 10 output buffers. A BCD code applied to the four input, 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. It is suitable for code conversion, indicator-tube decoder and address decoding-memory selection control.
