HEF4040BP,652

Counter Dividers Overview

The HEF4040BP,652 is a 12-stage binary ripple counter manufactured by NXP USA Inc. It features a clock input (CP), an asynchronous master reset input (MR), and twelve fully buffered outputs (Q0 to Q11). The device advances on the HIGH-to-LOW transition of the clock signal. It operates within a supply voltage range of 3.0 V to 15.0 V and supports ambient temperatures from -40 °C to +85 °C. Inputs are overvoltage tolerant up to 15 V. Propagation delays vary with load capacitance; for example, CP to Q0 delay ranges from 78 ns at 5 V to 27 ns at 15 V under standard test conditions.

Counter Dividers Feature Summary

• Provides 12-stage binary counting capability with static toggle flip-flops
• Features overvoltage tolerant inputs allowing use in level shifting applications
• Includes an overriding asynchronous master reset input that clears all stages
• Complies with JEDEC standard JESD 13-B for CMOS logic

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify the specific package type against the datasheet ordering information. The HEF4040B family includes variants such as the SO16 plastic small outline package (HEF4040BT). Confirm that the requested suffix matches the required physical form factor and lead configuration for your design constraints before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counter is required for frequency division or timing control. Ensure the application voltage falls between 3.0 V and 15.0 V. Consider the propagation delay characteristics relative to the load capacitance if high-speed operation is necessary. Verify that the asynchronous reset functionality aligns with the system's timing requirements.

Counter Dividers Part Context

This part belongs to the HEF4040B series of 12-stage binary ripple counters. It is designed for general-purpose digital counting applications. The device utilizes CMOS technology for low power dissipation and high noise immunity. It is suitable for environments requiring robust performance across a wide temperature range.

Counter Dividers Replacement Considerations

Check for compatible parts within the same logic family. Ensure any substitute maintains the 12-stage count and similar pinout compatibility if direct replacement is intended.
