PIN AND FUNCTION COMPATIBLE

WITH 54/74LS688

The M54/74HCT688 utilizes silicon gate C

2MOS

technology to achieve operating speeds equivalent

to LSTTL devices. Along with the low power

dissipation and high noise immunity of standard

C

2MOS integrated circuit, it possesses the driving

capability of 10 LSTTL load. The M54/74HCT688

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 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

2MOS 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.
