HEF4040BT,652

Counter Dividers Overview

The HEF4040BT,652 is a 12-stage binary ripple counter manufactured by Nexperia USA Inc. It features a clock input (CP), an overriding asynchronous master reset input (MR), and twelve fully buffered outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all stages and forces outputs LOW. Inputs are overvoltage tolerant to 15 V. Recommended operating conditions specify a supply voltage range of 3.0 V to 15.0 V and an ambient temperature range of -40 °C to +85 °C.

Counter Dividers Feature Summary

• Features a 12-stage binary ripple counter with an asynchronous master reset input that overrides the clock signal to clear all stages.
• Provides twelve fully buffered parallel outputs and includes overvoltage tolerance up to 15 V for level shifting applications.
• Supports wide supply voltage operation from 3.0 V to 15.0 V with CMOS low power dissipation and high noise immunity.

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package variant. Check current product status as availability may vary. Ensure compliance with RoHS directives and relevant environmental regulations before integration into final designs.

Counter Dividers Selection Notes

Select this component for designs requiring a 12-bit asynchronous binary counter in surface-mount packaging. Verify that the logic family compatibility meets system requirements. Ensure the operating voltage range aligns with the application's power supply constraints. Consider the maximum frequency specifications relative to the intended clock speed.

Counter Dividers Part Context

This device belongs to the HEF4040B series of 12-stage binary ripple counters produced by Nexperia. It utilizes a plastic small outline package (SO16) with 16 leads. The series is designed for general-purpose digital counting applications within standard industrial temperature ranges.
