several MC10136 counters may be cascaded. The Carry In
input overrides the clock when the counter is either in the
increment mode or the decrement mode of operation. This
input allows several devices to be cascaded in a fully
synchronous multistage counter as illustrated in Figure 1.
The carry is advanced between stages as shown with no
external gating. The Carry In of the first device may be left
open. The system clock is common to all devices.
useful for a wide variety of applications. If used with MECL
III devices, prescalers with input toggle frequencies in
excess of 300 MHz are possible. Figure 2 shows such a
prescaler using the MC10136 and MC1670. Use of the
MC10231 in place of the MC1670 permits 200 MHz
operation.
To provide more than four bits of counting capability
The various operational modes of the counter make it

counter. The configuration of Figure 3 requires no additional
gates, although maximum frequency is limited to about 50
MHz. The divider modulus is equal to the program input
plus one (M = N + 1), therefore, the counter will divide by
a modulus varying from 1 to 16.
in Figure 4. A pulse swallowing technique is used to speed
the counter operation up to 110 MHz typically. The divider
modulus for this figure is equal to the program input (M =
N). The minimum modulus is 2 because of the pulse
swallowing technique, and the modulus may vary from 2 to
15. This programmable configuration requires an additional
gate, such as
