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 silicongate CMOS technology to achieve speed performance 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 12stage 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.

Note 4: For a power supply of 5V g 10% 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 VCC e 5.5V 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. 2 AC Electrical Characteristics VCC e 5V, TA e 25 C, CL e 15 pF, tr e tf e 6 ns Symbol Parameter Conditions Typ Guaranteed Limit Units 50 30 MHz 17 35 ns fMAX Maximum Operating Frequency tPHL, tPLH Maximum Propagation Delay Clock to Q tPHL Maximum Propagation Delay Reset to any Q 16 40 ns tREM Minimum Reset Removal Time 10 20 ns tW Minimum Pulse Width 10 16 ns (Note 5) AC Electrical Characteristics VCC e 2.0V to 6.0V, CL e 50 pF, tr e tf e 6 ns (unless otherwise specified) Symbol Parameter Conditions TA e 25 C VCC Typ 74HC TA eb40 to 85 C 54HC TA eb55 to 125 C Units Guaranteed Limits fMAX Maximum Operating Frequency 2.0V 4.5V 6.0V 10 40 50 6 30 35 5 24 28 4 20 24 MHz MHz MHz tPHL, tPLH Maximum Propagation Delay Clock to Q1 2.0V 4.5V 6.0V 80 21 18 210 42 36 265 53 45 313 63 53 ns ns ns TPHL, tPLH Maximum Propagation Delay Between Stages from Qn to Qn a 1 2.0V 4.5V 6.0V 80 18 15 125 25 21 156 31 26 188 38 31 ns ns ns tPHL Maximum Propagation Delay Reset to any Q ('4020 and '4040) 2.0V 4.5V 6.0V 72 24 20 240 48 41 302 60 51 358 72 61 ns ns ns tREM Minimum Reset Removal Time 2.0V 4.5V 6.0V 100 20 16 126 25 21 149 50 25 ns ns ns tW Minimum Pulse Width 2.0V 4.5V 6.0V 90 16 14 100 20 18 120 24 20 ns ns ns tTLH, tTHL Maximum Output Rise and Fall Time 2.0V 4.5V 6.0V 75 15 13 95 19 16 110 22 19 ns ns ns tr, tf Maximum Input Rise and Fall Time 1000 500 400 1000 500 400 1000 500 400 ns ns ns CPD Power Dissipation Capacitance (Note 6) CIN Maximum Input Capacitance 30 10 9 (per package) 55 5 pF 10 10 10 pF Note 5: Typical Propagation delay time to any output can be calculated using: tP e 17 a 12(N-1) ns; where N is the number of the output, QW, at VCC e 5V.
