MM74HC4020 • MM74HC4040
14-Stage Binary Counter • 12-Stage Binary Counter
General Description
The MM74HC4020, MM74HC4040, are high speed binary
ripple carry counters. These counters are implemented uti-
lizing 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.
The MM74HC4020 is a 14 stage counter and the
MM74HC4040 is a 12-stage counter. Both devices are
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.
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 VCC and
ground.
Features
