DESCRIPTION
TheHCC4028B(extended temperature range) and

HCF4028B (intermediate temperature range) are

monolithic integrated circuit, available in 16-lead
dual in-line plastic or ceramic package and plastic
micropackage.

The HCC/HCF4028B typesare BCD-to-decimal or
binary-to-octal decoders consisting of buffering on
all4inputs,decoding-logic gates,and10outputbuf­fers. A BCD code applied to thefourinputs, A to D,
resultsin a high level at the selected one of 10 de­cimaldecodedoutputs.Similarly,a3-bit binary code
applied to inputs A through C is decoded in octal
codeat output0 to 7ifD =”0”. Highdrive capability
isprovided atalloutputstoenhancedcand dynamic
performance inhigh fan-out applications.
