Overview
The 54LS155A/BEA is a dual 2-line to 4-line decoder/demultiplexer manufactured by Rochester Electronics. It operates within the LS logic family and supports a nominal voltage of 5V, with an operating range from 4.5V to 5.5V. The device features two independent channels, each decoding two select bits into four outputs. It is housed in a ceramic DIP-16 package and is rated for military-grade operation across a temperature range of -55°C to 125°C.
Feature Summary
- Dual channel architecture providing two independent 2-to-4 line decoding functions
- Military-grade reliability with extended temperature rating suitable for harsh environments
- Ceramic hermetic packaging ensuring durability and signal integrity
Applications
- Address decoding in military computing systems
- Data routing in aerospace communication equipment
- Signal demultiplexing in defense instrumentation
Procurement Notes
Verify that the specific suffix /BEA corresponds to the intended ceramic package variant. Confirm that the lot traceability meets QML MIL-PRF-38535 Class V requirements if space-level certification is mandated. Ensure the component matches the original OEM specifications guaranteed by Rochester Electronics.
