PIN AND FUNCTION COMPATIBLE

WITH 54/74LS688

The M54/74HC688 utilizes silicon gate C

2MOS

technology to achieve operating speeds equivalent

to LSTTL devices. Along with the low power dissi-

pation and high noise immunity of standard C

2MOS

integrated circuit, it possesses the driving capability

of 10 LSTTL load. The M54/74HC688 compares bit

for bit two 8-bit words applied on inputs P0 - P7 and

inputs Q0 - Q7 and indicates whether or not they are

equal. A single active 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.
