description
These identity comparators perform comparisons
of
two
8-bit
binary
or
BCD
words.
An
output-enable (OE) input may be used to force the
output to the high level.
The SN54HC688 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74HC688 is characterized for
operation from –40
°C to 85°C.
