14-Stage Binary Counter
12-Stage Binary Counter
General Description
The
MM54HC4020/MM74HC4020,
MM54HC4040/
MM74HC4040, are high speed binary ripple carry counters.
These
counters
are
implemented
utilizing
advanced
silicon-gate CMOS technology to achieve speed perfor-
mance similar to LS-TTL logic while retaining the low power
and high noise immunity of CMOS.
The ’HC4020 is a 14 stage counter and the ’HC4040 is a
12-stage counter. Both devices are incremented on the fall-
ing 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.
These devices are pin equivalent to the CD4020 and
CD4040 respectively. All inputs are protected from damage
due to static discharge by protection diodes to V
CC and
ground.
