74HC4020; 74HCT4020 14-stage binary ripple counter Rev. 7 — 18 June 2020 Product data sheet 1. General description The 74HC4020; 74HCT4020 is a 14-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and 12 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. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2. Features and benefits • Wide supply voltage range from 2.0 V to 6.0 V • CMOS low power dissipation • High noise immunity • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B • Complies with JEDEC standards: • JESD8C (2.7 V to 3.6 V) • JESD7A (2.0 V to 6.0 V) • Input levels: • For 74HC4020: CMOS level • For 74HCT4020: TTL level • ESD protection: • HBM JESD22-A114F exceeds 2000 V • MM JESD22-A115-A exceeds 200 V • Multiple package options • Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3. Applications • Frequency dividing circuits • Time delay circuits • Control counters
