DESCRIPTION
The HCC4028B (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 types are BCD-to-decimal or
binary-to-octal decoders consisting of buffering on
all 4 inputs, decoding-logic gates, and 10 output buf-
fers. A BCD code applied to the four inputs, A to D,
results in a high level at the selected one of 10 de-
cimal 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.
