MC14040BFR1

Counter Dividers Overview

The MC14040BFR1 is a 12-bit binary ripple counter and frequency divider manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and features a single clock input that triggers on the falling edge. The device provides twelve parallel outputs for binary counting or frequency division applications. It is housed in an SOIC-16 surface-mount package and supports operation across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Integrates a 12-stage ripple carry binary counter with dedicated parallel output pins
• Features internal waveform shaping circuitry for robust clock signal processing
• Supports asynchronous reset functionality to initialize the count sequence

Counter Dividers Applications

• Frequency division circuits
• Digital timing and delay generation
• Binary event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix 'FR1' against official manufacturer documentation, as standard listings often reference 'MC14040BD'. Confirm RoHS compliance status and current lifecycle stage, as this component may be discontinued or subject to limited availability constraints depending on the manufacturing batch.

Counter Dividers Selection Notes

Select this component when a high-density 12-bit counter is required in a compact surface-mount footprint. Ensure the design accommodates the propagation delays inherent to ripple counters rather than synchronous architectures. Verify that the operating voltage remains within the specified 3 V to 18 V limits for reliable CMOS logic performance.

Counter Dividers Part Context

This part belongs to the MC14040B family of 12-bit binary counters. It shares functional similarities with other members like the MC14040BD but differs in packaging and reel configuration. The series is designed for general-purpose digital logic applications requiring simple up-counting capabilities without complex synchronization requirements.

Counter Dividers Replacement Considerations

Direct substitutes include the MC14040BD and MC14040BCPG. Verify pin compatibility and electrical specifications before substitution.
