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 performance simi-
lar 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 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
Connection Diagrams
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
Y Typical propagation delay 16 ns
Y Wide operating voltage range 2 – 6V
Y Low input current 1 mA maximum
Y Low quiescent current 80 mA maximum (74HC Series)
Y Output drive capability 10 LS-TTL loads

Note 4 For a power supply of 5V g10% the worst case output voltages (VOH and VOL) occur for HC at 4 5V Thus the 4 5V values should be used when
designing with this supply Worst case VIH and VIL occur at VCCe5 5V and 4 5V respectively (The VIH value at 5 5V is 3 85V ) The worst case leakage current (IIN
ICC and IOZ) occur for CMOS at the higher voltage and so the 6 0V values should be used
VIL limits are currently tested at 20% of VCC The above VIL specification (30% of VCC) will be implemented no later than Q1 CY’89
