DM7130 Magnitude Comparators
General Description Features
This device offers comparisons to determine equality be- " Typical propagation delay 21 ns
tween two binary words. The DM7130 compares two ten-bit a Typical power dissipation 240 mW
words. A strobe override is provided. When the strobe is u Open-collector outputs for expansion
taken to a high logic level, the output is forced to a high
logic level. The device also features open collector outputs
for expansion.

Recommended Operating Conditions
Note: The "Absolute Maximum Ratings" are those values
beyond which the safety of the device cannot be guaran-
teed. The device should not be operated at these limits. The
parametric values defined in the "Electrical Characteristics"
table are not guaranteed at the absolute maximum ratings.
The "Recommended Operating Conditions" table will define
the conditions for actual device operation.
