HEF4020BT,653

Counter Dividers Overview

The HEF4020BT,653 is a 14-stage binary ripple counter from the Nexperia HEF4000B logic family. It features a clock input (CP) and an overriding asynchronous master reset input (MR). The device provides 12 buffered parallel outputs (Q0, Q3 to Q13), with stages advancing on the HIGH-to-LOW transition of CP. It operates within a supply voltage range of 3.0 V to 15.0 V and includes clamp diodes on inputs for interfacing with voltages exceeding VDD.

Counter Dividers Feature Summary

• Features fully static operation with CMOS low power dissipation and high noise immunity.
• Includes an overriding asynchronous master reset input that clears all counter stages independent of the clock state.
• Inputs incorporate clamp diodes to enable current limiting resistors for interfacing with voltages in excess of VDD.

Counter Dividers Applications

• Digital counting applications requiring 14-bit binary sequence generation.
• Frequency division circuits utilizing the ripple counter architecture.
• Timing and sequencing systems compatible with standard CMOS logic levels.

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm the temperature range aligns with operational requirements. Ensure the component status is active before finalizing design-in decisions. Cross-reference the datasheet revision date to ensure access to the latest electrical specifications and pinning details.

Counter Dividers Selection Notes

Select this component when a 14-stage binary counter is required within the HEF4000B family. It is suitable for designs needing buffered parallel outputs and an asynchronous master reset function. Consider the propagation delay characteristics relative to the maximum operating frequency and load capacitance for timing-critical applications.

Counter Dividers Part Context

This part belongs to the Nexperia HEF4000B series, which defines standardized symmetrical output characteristics and complies with JEDEC standard JESD 13-B. The 'BT' designation indicates the SO16 plastic small outline package (SOT109-1) with a body width of 3.9 mm, designed for surface mount technology.

Counter Dividers Replacement Considerations

Direct substitutes include other HEF4020 variants such as the HEF4020BP or HEF4020BTS if package compatibility allows. Verify functional equivalence regarding the 14-stage count and output buffering before substitution.
