Overview
The 54LS243/BCA is a high-performance octal bus transceiver manufactured by Rochester Electronics, LLC. It features dual directional control and three-state outputs for effective bus management. The component is dual marked as M38510/32802BCA, indicating compliance with MIL-PRF-38535 Class V specifications. It utilizes a ceramic dual in-line package (CDIP) suitable for space-level applications. The device ensures signal integrity across digital systems through reliable TTL-compatible logic levels.
Feature Summary
- Octal bidirectional data transfer capability
- Dual independent direction control inputs
- Three-state output design for bus isolation
- Military-grade ceramic packaging
Applications
- Space-level digital data routing
- High-reliability bus interface circuits
- Military communication system data buses
- Industrial control system I/O expansion
Procurement Notes
Verify the dual marking M38510/32802BCA on the component surface to confirm authenticity. Ensure the package type matches CDIP requirements for your board layout. Confirm that the supplier provides traceability documentation consistent with AS9120 or QML standards. Check for lead-free status if environmental compliance is required, as this specific variant may contain lead.
Selection Notes
Select this component when an octal bus transceiver with independent direction control is required for critical applications. It is suitable for designs needing robust noise immunity and high-speed switching. Consider the ceramic package for thermal stability and radiation hardness in harsh environments. Ensure voltage levels match the system's TTL logic family requirements.
Part Context
Rochester Electronics specializes in supplying qualified replacement semiconductors for legacy and military components. The 54LS243/BCA falls under their portfolio of aerospace and defense grade parts. These components are often sourced from original manufacturer wafers or recreated to meet strict MIL-PRF-38535 standards. This ensures continuity for systems requiring long-term availability and performance consistency.
Replacement Considerations
Direct substitutes include other MIL-PRF-38535 qualified octal bus transceivers with identical pinouts and electrical characteristics. Verify compatibility with existing PCB footprints and thermal management solutions. Ensure that any replacement maintains the same direction control logic and three-state behavior.
