MOTOROLA MC74HC4020AD

SEMICONDUCTOR TECHNICAL DATA
High–Performance Silicon–Gate CMOS
The MC74C4020A is identical in pinout to the standard CMOS
MC14020B. The device inputs are compatible with standard CMOS outputs;
with pullup resistors, they are compatible with LSTTL outputs.
This device consists of 14 master–slave flip–flops with 12 stages brought
out to pins. The output of each flip–flop feeds the next and the frequency at
each output is half of that of the preceding one. Reset is asynchronous and
active–high.
State changes of the Q outputs do not occur simultaneously because of
internal ripple delays. Therefore, decoded output signals are subject to
decoding spikes and may have to be gated with the Clock of the HC4020A
for some designs.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.

* For TA = 25°C and CL = 50 pF, typical propagation delay from Clock to other Q outputs may be calculated with the following equations:
VCC = 2.0 V: tP = [93.7 + 59.3 (n–1)] ns
VCC = 4.5 V: tP = [30.25 + 14.6 (n–1)] ns
VCC = 3.0 V: tP = [61.5 + 34.4 (n–1)] ns
VCC = 6.0 V: tP = [24.4 + 12 (n–1)] ns
Typical @ 25°C, VCC = 5.0 V

APPLICATIONS INFORMATION
Time–Base Generator
feeds the HC4020A. Selecting outputs Q5, Q10, Q11, and
Q12 causes a reset every 3600 clocks. The HC20 decodes
the counter outputs, produces a single (narrow) output pulse,
and resets the binary counter. The resulting output frequency
is 1.0 pulse/minute.
A 60Hz sinewave obtained through a 1.0 Megohm resistor
connected directly to a standard 120 Vac power line is
applied to the input of the MC54/74HC14A, Schmitt-trigger
inverter. The HC14A squares–up the input waveform and
