12-Stage Binary Ripple Counter

ON Semiconductor 

MC74HC4040A

12-Stage Binary Ripple

Counter

High−Performance Silicon−Gate CMOS

The MC74C4040A is identical in pinout to the standard CMOS

MC14040. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LSTTL

outputs.

This device consists of 12 master−slave flip−flops. The output of

each flip−flop feeds the next and the frequency at each output is half of

that of the preceding one. The state counter advances on the

negative−going edge of the Clock input. Reset is asynchronous and

active−high.

State changes of the Q outputs do not occur simultaneously because

of internal ripple delays. Therefore, decoded output signals are subject

to decoding spikes and may have to be gated with the Clock of the

HC4040A for some designs.
