12-STAGE BINARY COUNTER
The MM74HC4040 is a high speed binary ripple carry counter. This counter is implemented utilizing advanced silicon-gate CMOS technology to achieve speed performance similar to LS-TTL logic while retaining the low power and high noise immunity of CMOS. This device increments on the falling edge (negative transition) of the input clock, and all the outputs are reset to a low level by applying a logical high on the reset input.
Typical propagation delay: 16 ns
Wide operating voltage range: 2-6V
Low input current: 1 µA maximum
Low quiescent current: 80 µA maximum
Output drive capability: 10 LS-TTL loads
