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.
