MM74HC4020 • MM74HC4040
14-Stage Binary Counter • 12-Stage Binary Counter
General Description
The MM74HC4020, M M74HC4040 , are high spe ed binary
ripple carry counters . These counters are i mple me nte d u tilizing advanced silicon- gate CMOS technology to ach ieve
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 t he
input clock, and all th eir outp uts ar e reset to a l ow leve l 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 pr otection diodes to V
CC
and
ground.
Features
■ Typical propagation delay: 16 ns
■ Wide operating voltage range: 2–6V
■ Low input current: 1 µA maximum
■ Low quiescent current: 80 µA maximum (74HC Series)
■ Output drive capability: 10 LS-TTL loads

Recommended Operating
Conditions
Note 1: Maximum Ratings are those values beyond which damage to the
device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.
Note 3: Power Dissipation te mperature d erating — pl astic “N” pa ckage: −
12 mW/°C from 65°C to 85°C.
DC Electrical Characteristics (Note 4)
Note 4: For a powe r supply o f 5V ±10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4. 5V valu es shou ld be u sed when
designing with this supply. Worst case V
IH
and VIL occur at V
CC
= 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3 .8 5V.) The worst c as e leakage cur-
rent (I
IN
, ICC, and IOZ) occur for CMOS at the higher voltage and so th e 6. 0V values should be used.
