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. It is also suitable for use over the full industrial (−40 °C to +85 °C) temperature range.

■ High speed operation
■ Fully static operation
■ 5 V, 10 V, and 15 V parametric ratings
■ Standardized symmetrical output characteristics
■ Operates across the full industrial temperature range −40 °C to +85 °C
■ Complies with JEDEC standard JESD 13-B
■ ESD protection:
   ◆ HBM JESD22-A114E exceeds 2000 V
   ◆ MM JESD22-A115-A exceeds 200 V
■ Industrial
