74LV4020
Datasheet
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.
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 =25Cel
- Typical HIGH-level output voltage (valley) or output VOH undershoot: VOH(v) >2 V at VCC = 3.3 V and Tamb =25Cel
- ESD protection:
- HBM EIA/JESD22-A114-C exceeds 2000 V
- MM EIA/JESD22-A115-A exceeds 200 V.
- Multiple package options
- Specified from -40 Cel to +80 Cel and from -40 Cel to +125 Cel.
