14-stage binary ripple counter
74HC/HCT4020
FEATURES
Output capability: standard
ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT4020 are high-speed Si-gate CMOS
devices and are pin compatible with the “4020” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4020 are 14-stage binary ripple counters
with a clock input (CP), an overriding asynchronous
master reset input (MR) and twelve fully buffered parallel
outputs (Q0, Q3 to Q13).
The counter is advanced on the HIGH-to-LOW transition of
CP.
A HIGH on MR clears all counter stages and forces all
outputs LOW, independent of the state of CP.
Each counter stage is a static toggle flip-flop.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf = 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W):
PD =CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC 1.5 V
