Overview
The 54366AJ/B is a high-current HEX bus driver manufactured by Rochester Electronics, LLC. It consists of two fully integrated drivers with three-state outputs, designed to drive a sink current of 64 mA per element. The device utilizes a 16-pin SOIC package (PLASTIC, SO-16) and features 2 functional units. Built-in protections include overvoltage, thermal, and transient safeguards. The component operates in source and sink modes and is certified for commercial use.
Feature Summary
- Integrates two high-current HEX bus drivers with three-state output capability
- Provides 64-mA sink current per element for robust signal driving
- Includes built-in protection against overvoltage, thermal stress, and transients
Applications
- Three-state memory address drivers
- High-density digital logic interfaces
- Bus line buffering applications
Procurement Notes
Verify the authenticity of the 54366AJ/B through authorized distributors or direct manufacturer channels. Confirm that the part matches the original Infineon specifications, as Rochester Electronics provides lifecycle support for legacy components. Ensure the package type is SOIC-16 and check for any specific ordering suffixes that may indicate temperature range or tape-and-reel configuration. Request test reports if required for critical automotive or industrial validation.
Selection Notes
Select this component when designing systems requiring high-current bus driving with three-state isolation. The 64-mA sink capability supports heavy capacitive loads typical in memory addressing. Consider the SOIC-16 footprint for PCB layout constraints. Verify compatibility with system voltage levels and ensure thermal management aligns with the built-in protection features for continuous operation.
Part Context
Rochester Electronics specializes in sustaining production for end-of-life semiconductors. The 54366AJ/B represents continued support for legacy Infineon HEX bus drivers. This ensures long-term availability for industrial and automotive platforms where redesigning around obsolete components is not feasible. The part maintains original performance characteristics under Rochester's quality standards.
Replacement Considerations
Direct substitutes include other HEX bus drivers with three-state outputs and similar current ratings. Verify pinout compatibility before swapping. Generic equivalents may lack the specific 64-mA sink specification or built-in transient protection found in the original design.
