12-Stage Binary Counter
Features General Description
Typical propagation delay: 16ns The MM74HC4040 is a high speed binary ripple carry
counter. This counter is implemented utilizing advanced
Wide operating voltage range: 26V
silicon-gate CMOS technology to achieve speed perfor-
Low input current: 1A Max.
mance similar to LS-TTL logic while retaining the low
Low quiescent current: 80A Max. (74HC Series)
power and high noise immunity of CMOS.
Output drive capability: 10 LS-TTL loads
The MM74HC4040 is a 12-stage counter. This device is
incremented on the falling edge (negative transition) of
the input clock, and all their outputs are reset to a low
level by applying a logical high on their reset input.
This device is pin equivalent to the CD4040. All inputs
are protected from damage due to static discharge by
protection diodes to V and ground.
