General Description

The NC7S86 is a sing le 2-Input high perfor mance CMOS
Exclusive-OR Gate. Advanced Silicon Gate CMOS fabrica­tion assures high speed and low po wer circuit operation
over a broad V

guard both inputs an d output with respect to the V
GND rails. Inputs are well buffered from the output to

assure high noise immunity and reduced sensitivity to input
edge rate.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with­out exception, to ensure that the system design is reliable over its power
