Functional Features

• High-speed operation allows for efficient counting and dividing.
• Low power consumption makes it suitable for battery-powered devices.
• Master Reset (MR) pin allows for resetting the counter to its initial state.
• Clock Pulse (CP) pin triggers the counting operation.
• Ripple-carry output enables cascading multiple counters.

Advantages

• Compact and space-saving SOIC package.
• Wide supply voltage range provides flexibility in different applications.
• High-speed operation allows for quick counting and dividing tasks.
• Low power consumption prolongs battery life in portable devices.

Disadvantages

• Limited number of stages (14) may not be sufficient for complex counting applications.
• Lack of built-in oscillator requires an external clock source.

Working Principles

The HEF4020BT-Q100J is a 14-stage ripple-carry binary counter/divider and oscillator. It counts the number of clock pulses applied to the CP pin and produces binary outputs on the Q0-Q9 pins. The counter can be reset to its initial state by applying a low signal to the MR pin. The ripple-carry output allows for cascading multiple counters to achieve higher counting ranges.

Detailed Application Field Plans

• Frequency division in digital circuits.
• Timekeeping and clock generation.
• Event counting and timing applications.
• Industrial automation and control systems.
• Communication equipment and data processing.
