MD82C87H-5/883

The MD82C87H-5/883 is an octal bus transceiver with inverting 3-state outputs manufactured by Renesas Electronics, designed to provide bidirectional data transfer between an 8-bit system bus and peripherals in high-reliability environments. Built using high-speed CMOS technology, the device delivers inverting B-port outputs with strong 3-state drive capability, enabling reliable operation on heavily loaded backplanes and multi-board bus structures. Supplied in a 20-pad ceramic leadless chip carrier (CLCC) package, the /883 suffix indicates full conformance to MIL-STD-883 Class B screening, which includes rigorous burn-in, temperature cycling, and hermetic seal testing to guarantee performance over the full military temperature range of -55°C to +125°C.

This part is deployed extensively in avionics mission computers, satellite bus interface modules, and ruggedized defense communication platforms where deterministic signal inversion and long-term reliability under shock and vibration are critical requirements. The inverting output stage simplifies active-low control interfaces and negative-true data paths without additional discrete logic. Procurement staff should note that military-grade logic components of this class can face extended lead times and diminishing supply as manufacturers rationalize legacy product lines, making obsolescence planning and lifetime-buy qualification important early steps. Authentic devices must carry full traceability from the original manufacturer, matched to the applicable MIL-STD-883 slash-sheet compliance documentation, and should be sourced through authorized channels to eliminate counterfeit exposure.
