DESCRIPTION
The M54/74HC688 utilizes silicon gate C
2
MOS
technology to achieve operating speeds equivalent
to LSTTL devices. Along with the low power dissi-
pationand high noiseimmunity of standard C
2
MOS
integrated circuit,it possesses the driving capability
of 10LSTTL load. TheM54/74HC688 compares bit
for bit two 8-bit words applied on inputs P0 -P7and
inputsQ0-Q7andindicates whether ornottheyare
equal. A singleactive low enable is provided to fa-
cilitate cascading several packages to enable com-
parison of words greater than 8 bits. All inputs are
equipped with protection circuit against static dis-
charge and transient excess voltage.
