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
A>B A<B A = B

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.
