54HC160/BEA

Overview

The 54HC160/BEA is a synchronous 4-bit binary counter manufactured by Rochester Electronics, LLC. It features an asynchronous reset and operates within the HC/UH logic series. The device supports up-counting direction and includes load/preset inputs for parallel data entry. It is designed for high-speed CMOS applications with negative edge triggering. The component is available in a CDIP-14 package and is characterized for operation over the military temperature range of -55°C to 125°C.

Feature Summary

• Synchronous 4-bit binary counting capability with up-direction support
• Asynchronous reset function for immediate clearing of count states
• Parallel load input allowing direct presetting of counter values
• Negative edge-triggered operation compatible with HC/UH logic standards

Applications

• Military-grade digital timing systems requiring extended temperature tolerance
• High-reliability aerospace control circuits utilizing ceramic packages
• Industrial automation counters operating under harsh environmental conditions
• Defense electronics requiring qualified manufacturer list (QML) components

Procurement Notes

Verify that the specific unit matches the 54HC160/BEA designation, as Rochester Electronics often supplies dual-marked parts such as 5962-8682401EA. Confirm the package type is CDIP-14 and check for QML MIL-PRF-38535 Class Q certification if military qualification is required. Ensure the lead time aligns with lifecycle status expectations for end-of-life or surplus inventory items.

Selection Notes

Select this component when a synchronous 4-bit counter with asynchronous reset is needed for military or industrial environments. The HC/UH series ensures compatibility with standard high-speed CMOS logic levels. The ceramic CDIP-14 package provides superior thermal stability and hermetic sealing compared to plastic alternatives, making it suitable for applications where reliability under extreme temperatures is critical.

Part Context

Rochester Electronics specializes in providing lifecycle solutions for semiconductors, including end-of-life and obsolete parts. They manufacture components using original supplier dies or recreated IP approved by Original Component Manufacturers (OCM). This part falls under their portfolio of qualified military and industrial grade devices, ensuring performance meets or exceeds original datasheet specifications through rigorous testing programs.

Replacement Considerations

Direct substitutes include other 54HC160 variants from different manufacturers that meet the same electrical and pinout specifications. For military applications, verify if alternative parts hold equivalent QML or MIL-PRF-38535 certifications. Ensure any replacement maintains the synchronous counting architecture and asynchronous reset functionality.
