Overview
The 54F821/Q3A is a 10-bit non-inverting shift register manufactured by Rochester Electronics, LLC. It belongs to the 54F series of logic components and features TTL-compatible CMOS input levels. The device operates within a standard military temperature range and is housed in a ceramic dual in-line package (CDIP). This component is designed for high-reliability applications requiring serial-to-parallel or parallel-to-serial data conversion capabilities.
Feature Summary
- Provides 10-bit serial-in, parallel-out data shifting functionality
- Features TTL-compatible CMOS inputs for versatile interfacing
- Constructed with non-inverting output stages
Applications
- Military aerospace data handling systems
- High-reliability industrial control interfaces
- Defense communication equipment signal processing
Procurement Notes
Verify the manufacturer date code and lot traceability upon receipt. Confirm the physical package integrity and pin alignment match the CDIP specification. Ensure storage conditions adhere to the specified Moisture Sensitivity Level 3 requirements to prevent internal damage before soldering.
Selection Notes
Select this component when a 10-bit shift register with military-grade reliability is required. It is suitable for designs needing TTL-compatible inputs in a CMOS environment. Consider the ceramic package for superior thermal and mechanical stability compared to plastic alternatives in harsh environments.
Part Context
This part is a dual-marked unit identified as 5962-89438013A. It is produced by Rochester Electronics, LLC, which specializes in legacy and obsolete semiconductor components. The 54F series denotes a specific speed-power trade-off characteristic of the original Fairchild Semiconductor design lineage.
Replacement Considerations
Direct substitutes include other 54F821 variants from different manufacturers that meet the same JEDEC standards. Verify pin compatibility and electrical specifications before replacing. Cross-reference with 5962-89438013A markings for equivalent performance.
