Details
The HEF4020B is a 14-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (O0, O3 to O13). 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 HEF4020B is: high speed (typ. 35 MHz at VDD = 15 V).
Key Features
- 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

FAQs
What is HEF4020BP?
The HEF4020BP is a 14-stage binary counter integrated circuit (IC) manufactured by NXP Semiconductors. It is commonly used in various digital counting and frequency division applications, such as clock generation, frequency synthesis, and event counting.
How Does HEF4020BP Work?
The HEF4020BP works by counting the number of input clock pulses and generating a binary output representing the count value. It features a 14-stage ripple carry binary counter with a divide-by-2n output. The IC can operate with a wide range of input clock frequencies, making it suitable for diverse counting applications.
How Many Pins does HEF4020BP have and What are the Functions of the Pinout Configuration?
The HEF4020BP is housed in a 16-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- CP: Clock input pin for counting.
- MR: Master reset input pin for clearing the count.
- Q0 - Q13: Binary output pins representing the count value.
- VDD: Positive power supply pin.
- VSS: Ground pin.
What are the Pros and Cons of HEF4020BP?
Pros:
- High Counting Stages: Features a 14-stage binary counter for extended counting capabilities.
- Wide Operating Frequency Range: Supports a wide range of input clock frequencies for versatility.
- Simple Interface: Easy to use with straightforward clock and reset inputs.
- Cost-Effective: Provides cost-effective counting and division solutions for digital systems.
Cons:
- Non-Synchronous Operation: The counter stages operate asynchronously, which may require additional logic for synchronous applications.
- Limited Additional Features: May require external logic for advanced counting functions or input conditioning.
Are There Any Equivalents/Alternatives to HEF4020BP for Recommendation?
- The CD4020 from Texas Instruments is an equivalent 14-stage binary counter IC.
