DM7160 Magnitude Comparator
General Description
This device offers comparisons to determine equality be-
tween two binary words The DM7160 compares two six-bit
words A strobe override is provided When the strobe is
taken to a high logic level the output is forced to a high
logic level The device also features open-collector outputs
for expansion
Features
Y Typical propagation delay 21 ns
Y Typical power dissipation 205 mW
Y Open-collector outputs for expansion
