Overview
The 54LS295B/BCA is a military-grade, 4-bit Parallel In Parallel Out shift register from the LS TTL series. It features right-direction shifting with true outputs and three-state logic capabilities. The device is housed in a CQCC20 ceramic chip carrier package, designed for operation within an extended temperature range of -55°C to 125°C. Manufactured by Rochester Electronics, it adheres to original OEM specifications for reliability in harsh environments.
Feature Summary
- Supports parallel data loading and serial shifting operations with right-direction control
- Features three-state outputs for bus-oriented system designs
- Constructed in a hermetically sealed ceramic package for environmental durability
Applications
- Military aerospace digital signal processing systems
- High-reliability industrial data storage registers
- Harsh environment communication interface buffers
Procurement Notes
Verify the specific suffix BCA indicates the ceramic chip carrier package configuration. Confirm that the component meets MIL-STD requirements if applicable to your system design. Ensure compatibility with existing TTL logic levels and power supply constraints before integration into final assemblies.
Selection Notes
Select this component when military-grade reliability and extended temperature performance are required. The ceramic package offers superior protection against moisture and mechanical stress compared to plastic alternatives. Ideal for applications where long-term stability and radiation hardness are critical design parameters.
Part Context
Rochester Electronics specializes in sustaining obsolete and hard-to-find semiconductor products. This part is produced using licensed technology and original wafer sources, ensuring performance equivalence to the initial manufacturer's specifications. It serves as a reliable source for legacy military and industrial logic components no longer in primary production.
Replacement Considerations
Direct substitutes include other 54LS295 variants from different manufacturers, provided they match the CQCC20 package and electrical characteristics. Verify pinout compatibility and thermal management requirements when transitioning between suppliers or package styles.
