It packs six independent inverter gates into a 16-SOIC surface-mount package, each with a single input. The part operates across a 3V to 18V supply range, making it a natural fit for battery-powered or wide-rail industrial logic where the tighter 5V-only 74HC family would need a regulator. Quiescent current maxes at 4 µA, so it adds negligible draw in always-on sections. ## Output drive and speed — what the numbers mean for your BOM Each output can source 4.3 mA and sink 24 mA. Propagation delay is 50 ns at 15V with a 50 pF load. ## Temperature grade and environment Rated for -55°C to 125°C, the CD4049UBDT covers military and industrial extremes — avionics, satellite, downhole instrumentation, or outdoor telecom cabinets where the ambient can swing from a cold soak to engine-bay heat. The 4000B series is well-known for latch-up immunity and noise margin at high supply voltages, which is why it persists in legacy avionics and defence BOMs. ## Package and handling Supplied in a 16-SOIC (0.154\" body width, 3.90 mm) — the standard small-outline footprint for this logic density. Cut Tape (CT) is also listed for prototype or low-volume builds. No exposed pad; standard SOIC reflow profile applies.","metaTitle":"CD4049UBDT 4000B Inverter, 6-ch, 3V-18V, 16-SOIC","metaDescription":"CD4049UBDT hex inverter from TI 4000B series. 3V to 18V supply, -55°C to 125°C, 4.3mA/24mA output.
