What this 8-input expandable gate does on the board
The Texas Instruments CD4048BM96 is a 4000B-series CMOS multifunction expandable gate that takes eight inputs and delivers a single-ended output. The 'expandable' means you can cascade multiple devices to build wider logic functions — AND, OR, NAND, NOR — without adding discrete gate packages. Supply runs from 3V to 18V, so it sits comfortably alongside 5V logic or 12V industrial rails. The output sinks and sources 6.8 mA, enough to drive a CMOS load or a low-power relay coil through a transistor buffer. The military temperature range (-55°C to 125°C) tells you this part was designed for environments where commercial plastic logic would fail: avionics black boxes, satellite power controllers, downhole instrument cans, or engine-bay sensor interfaces. The 16-SOIC footprint is standard for board-level assembly; the wide-body 0.154-inch width keeps pin spacing comfortable for manual rework or inspection.
Temperature grade and what it means for procurement
Lifecycle status is active per the manufacturer, with ROHS3 compliance on the current build. No last-time-buy notice or successor part is on record, so this remains a safe line-item for new designs that need a rugged, wide-voltage logic gate.
Sourcing reality — what to expect on the BOM line
The CD4048BM96 is an active, current-production part from Texas Instruments. For a BOM line, this part does not carry the risk of a forced redesign or a last-time-buy scramble.
