Description

CD4028BMS 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.

The CD4028BMS is supplied in these 16-lead outline packages:

Braze Seal DIP H4S
Frit Seal DIP H1E
Ceramic Flatpack H3X

Applications

    • Code Conversion
    • Indication-Tube Decoder
    • Address Decoding - Memory Selection Control

Design Tip

Are the Schottky clamp diodes required on the outputs when not driving MOSFETs?
