74LV4020  
14-stage binary ripple counter  
Rev. 01 — 29 November 2005  
Product data sheet  
1. General description  
The 74LV4020 is a low-voltage Si-gate CMOS device and is pin and function compatible  
with the 74HC4020 and 74HCT4020.  
The 74LV4020 is a 14-stage binary ripple counter with a clock input (CP), an overriding  
asynchronous master reset input (MR) and 12 fully buffered parallel outputs (Q0, and  
Q3 to Q13).  
The counter advances 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.  
2. Features  
Optimized for low-voltage applications: 1.0 V to 5.5 V  
Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V  
Typical LOW-level output voltage (peak) or output ground bounce: VOL(p) < 0.8 V at  
VCC = 3.3 V and Tamb = 25 °C  
Typical HIGH-level output voltage (valley) or output VOH undershoot: VOH(v) > 2 V at  
VCC = 3.3 V and Tamb = 25 °C  
ESD protection:  
HBM EIA/JESD22-A114-C exceeds 2000 V  
MM EIA/JESD22-A115-A exceeds 200 V.  
Multiple package options  
Specified from 40 °C to +80 °C and from 40 °C to +125 °C.  
3. Applications  
Frequency dividing circuits  
Time delay circuits  
Control counters
