DESCRIPTION
The M54/74HCT688 utilizes silicon gate C
2
MOS
technology to achieve operating speeds equivalent
to LSTTL devices. Along with the low power
dissipation and high noise immunity of standard
C
2
MOS integrated circuit, it possesses the driving
capability of 10 LSTTL load. The M54/74HCT688
compares bitforbittwo8-bit wordsapplied on inputs
P0 - P7 and inputs Q0 - Q7 and indicates whether
or not they are equal. A single active low enable is
provided to facilitate cascading several packages to
enable comparison of words greater than 8 bits.
This integrated circuit has input and output
characteristics that are fully compatible with 54/74
LSTTL logic families. M54/74HCT devices are
designed to directly interface HSC
2
MOS systems
with TTL and NMOS components. They are also
plug in replacements for LSTTL devices giving a
reduction of power consumption.
All inputs are equipped with protection circuit
against static discharge and transient excess
voltage.
