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 pack-

ages:

Braze Seal DIP

Frit Seal DIP

H4S

H1E

Ceramic Flatpack H3X

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
