HEF4020B
14-stage binary counter
Rev. 8 — 18 November 2011
Product data sheet
1. General 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.
2. Features and benefits
