DM7160 Magnitude Comparator General Description Features This device offers comparisons to determine equality between 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.
