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.
