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.

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device
reliability.
