Its 3V to 18V supply span means it can run directly off a 12V industrial rail or a 9V battery without a regulator — a practical advantage for panel controls, motor drive interface logic, and remote sensor nodes where a clean 5V or 3.3V rail isn't guaranteed. The push-pull output stage delivers 3.4mA source and 20.4mA sink, typical for 4000B CMOS and sufficient to drive subsequent logic inputs or a small LED indicator. For driving longer traces or capacitive loads, budget extra decoupling at the output pin to keep edge rates clean. Rated across the full military temperature range, this part is at home in avionics black boxes, outdoor telecom cabinets, and downhole instrumentation where the ambient can swing from a cold soak to engine-bay heat. The 16-SOIC body is surface-mount, so the board sees the same thermal expansion as the part — no hermetic can needed unless the environment calls for sealed modules. Keep the soldering profile within the MSL rating of the package (typically MSL 1 for 4000B SOIC) to avoid moisture-related cracking during reflow. ## Lifecycle and sourcing For dual-sourcing resilience, the 4000B family has broad cross-shipment from multiple manufacturers, though the CD4502BM's specific inverting buffer function is less common than the non-inverting 4050. If you need a non-inverting buffer with similar supply range, the CD4050 is a functional alternative but not a pin-for-pin swap — verify the logic sense in your schematic.","metaTitle":"CD4502BM Buffer Inverter IC, 3V-18V, 16-SOIC","metaDescription":"CD4502BM 4000B series buffer inverter IC. 3V to 18V supply, -55°C to 125°C, push-pull output.
