MC14569BDWG

Counter Dividers Overview

The MC14569BDWG is a dual 4-bit binary/BCD down counter manufactured by onsemi. It operates within a supply voltage range of 3 V to 18 V and features a wide operating temperature range from -55 °C to +125 °C. The device is housed in a 16-SOIC (0.300", 7.50mm) package with an industrial temperature grade. Key electrical characteristics include a maximum propagation delay of 560 ns at 15 V, ensuring reliable performance in digital counting applications requiring programmable divide-by-N functionality.

Counter Dividers Feature Summary

• Dual independent 4-bit counters supporting both binary and BCD counting modes
• Programmable divide-by-N capability for frequency synthesis applications
• Wide operating voltage range suitable for diverse logic families
• Industrial temperature rating for harsh environment reliability

Counter Dividers Applications

• Frequency synthesizer circuits
• Digital clock dividers
• Programmable timing generators
• Counting systems requiring BCD output

Counter Dividers Procurement Notes

Verify the specific suffix 'DWG' corresponds to the SOIC-Wide-16 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or material declarations prior to integration. Ensure ESD handling protocols are followed during assembly due to CMOS sensitivity.

Counter Dividers Selection Notes

Select this component when dual independent down-counting channels are required in a single package. It is suitable for designs needing programmable division ratios in binary or decimal formats. Consider the 16-pin SOIC footprint for PCB layout constraints. Verify that the 3V to 18V supply range aligns with the system power architecture.

Counter Dividers Part Context

This part belongs to the MC14569B series of programmable counters. It serves as a functional alternative to other 4-bit down counters like the HEF4522B or HEF4526B. The device integrates two complete 4-bit counters with preset capabilities, offering a compact solution for complex digital sequencing tasks compared to discrete counter implementations.

Counter Dividers Replacement Considerations

Public confirmed substitutes include MC14569BCP and MC14569BCPG from onsemi. Cross-brand equivalents such as HEF4522B (dual BCD) or HEF4526B (dual binary) may be considered if pin compatibility and logical function match the design requirements.
