74177N

Overview

The 74177N is a 4-bit binary counter manufactured by Rochester Electronics, LLC. It operates within an ambient temperature range of -40°C to 85°C and utilizes surface mount technology. The component is classified under Counters and Dividers logic integrated circuits. This specific part number is currently listed as having new original stock available from the manufacturer.

Applications

• Digital counting systems
• Frequency division circuits
• Binary sequence generation

Procurement Notes

Verify the RoHS compliance status and moisture sensitivity level (MSL) before integration, as documentation indicates potential variations in environmental certification for this specific manufacturer lot. Confirm the package type matches the target PCB footprint requirements. Ensure the operating voltage specifications align with the system design constraints prior to final procurement approval.

Selection Notes

Select this component when a standard 4-bit binary counter functionality is required in a surface mount configuration. Consider the -40°C to 85°C industrial temperature rating for environments with moderate thermal fluctuations. Verify that the logic family characteristics meet the interface requirements of the host system. Check current stock availability as distribution channels may vary.

Part Context

Rochester Electronics specializes in supplying obsolete and hard-to-find semiconductor components, often acting as a secondary source for parts no longer actively produced by original equipment manufacturers. The 74177N falls under their inventory of legacy logic devices, providing continuity for designs requiring this specific 4-bit counter architecture.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives from other manufacturers if supply chain risks are identified. Verify electrical parameters such as propagation delay and output drive current against the original specification sheet to ensure functional equivalence in the existing circuit design.
