HCF4040BEY

Counter Dividers Overview

The HCF4040BEY is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology, functioning as a 12-stage ripple-carry binary counter and divider. It comprises master-slave flip-flops where the state advances on negative input pulse transitions. The device features buffered inputs and outputs with Schmitt trigger action, allowing unlimited clock rise and fall times. It operates within standard parametric ratings for 5V, 10V, and 15V supplies, with quiescent current specified up to 20V. The component meets JEDEC JESD13B standards for B series CMOS devices.

Counter Dividers Feature Summary

• 12-stage ripple-carry binary counter architecture using master-slave flip-flops

• General-purpose digital logic counters

Counter Dividers Procurement Notes

Verify the specific suffix 'BEY' against official STMicroelectronics documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating voltage ranges and temperature grades. Confirm that the component meets the necessary JEDEC JESD13B standards for your application environment. Cross-reference the part number with current availability status as product lines may undergo lifecycle changes.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counter with Schmitt trigger inputs is required for robust signal processing. It is suitable for designs needing buffered outputs and common reset functionality. Consider the medium speed operation characteristics and power supply requirements. Ensure the application environment aligns with the specified operating conditions and package constraints defined in the datasheet.

Counter Dividers Part Context

The HCF4040BEY belongs to the HCF4000B series of CMOS logic devices manufactured by STMicroelectronics. This series is designed for general-purpose digital applications, offering high noise immunity and low power consumption. The BEY suffix typically denotes a specific packaging configuration, such as a DIP variant, intended for through-hole mounting. These components are widely used in industrial and consumer electronics for basic digital logic functions.

Counter Dividers Replacement Considerations

Compatible substitutes include other 12-stage binary counters from the same family, such as the HCF4040B or HCF4040BC1. Verify pinout compatibility and electrical specifications before substitution. Alternative manufacturers may offer equivalent parts, but ensure they meet the same JEDEC standards and performance criteria.
