Description

In the HCC/HCF4070B and HCC/HCF4077B series, the HCC4070B/4077B (extended temperature range) and HCF4070B/4077B (intermediate temperature range) are monolithic integrated circuits, available in 14-lead dual in-line plastic or ceramic package and plastic micropackage.The HCC/HCF4070B contains four independent exclusive- OR gates.The HCC/HCF4077B contains four independent exclusive- NOR gates.

The HCC/HCF4070B and HCC/HCF4077B provide the system designer with a means for direct implementation of the exclusive-OR and exclusive- NOR function, respectively. For applications as Logical comparators, Adders/subtractors, Parity generators and checkers.
