Division by 5, or 8 occurs when any one or all of the five gate
inputs E1 through E5 are high. Division by 6, or 9 occurs
when all inputs E1 through E5 are low. (Unconnected MTTL
inputs are normally high, unconnected MECL inputs are
normally low). With the addition of extra parts, many different
division configurations may be obtained.
In their basic form, these devices will divide by 5/6 or 8/9.
