Description
The HEF4020B is a 14-stage binary counter with a clock input (¬CP), an overriding asynchronous master reset input (MR) and twelve fully buffered 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. A feature of the device is its high speed (typ. 35 MHz at VDD = 15 V).
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
