Hermetic bus transceiver for harsh environments
The AM26S12A/BEA is a 4-bit bus transceiver with inverting logic, packaged in a hermetic 16-lead ceramic DIP (CDIP). It handles bidirectional data flow on a single bus line, with the inverting output polarity simplifying certain bus-arbitration and parity-checking schemes. The part is built for the -55°C to 125°C military temperature range, making it a fit for avionics, missile guidance, satellite telemetry, and downhole instrumentation where sealed ceramic packages and wide thermal margins are mandatory.
Lifecycle and compliance
Listed as Active on the lifecycle status, meaning the manufacturer continues to produce the part. RoHS non-compliant (leaded solder dip on the ceramic package), which is typical for hermetic military-grade devices. If your BOM requires RoHS exemption for high-reliability applications, this part fits that exemption category. No official second source or successor is recorded; the part is sourced to order through independent distribution.
