LOGIC DIAGRAM

For longer word lengths, the MC10H166 can be serially

expanded or cascaded. Figure 1 shows two devices in a

serial expansion for a 9–bit word length. The A > B and

A < B outputs are fed to the A0 and B0 inputs respectively

of the next device. The connection for an A = B output is

also shown. The worst case delay time of serial

expansion is equal to the number of comparators times

the data–to–output delay.
