MM54HC4020/MM74HC4020

14-Stage Binary Counter

MM54HC4040/MM74HC4040

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.

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

YTypical propagation delay: 16 ns

YWide operating voltage range: 2–6V

YLow input current: 1 mA maximum

YLow quiescent current: 80 mA maximum (74HC Series)

YOutput 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.
