CD40106BF3A

The Texas Instruments CD40106BF3A is a military-grade CMOS hex inverting Schmitt-trigger logic device housed in a 14-pin ceramic dual-in-line package (CDIP-14). Each of the six independent inverters incorporates Schmitt-trigger inputs with hysteresis, allowing the part to transform slowly changing or noisy signals into clean, sharply defined output transitions. Built on a 4000-series CMOS process, the device operates across a wide supply voltage range, typically from 3 V to 18 V, and delivers the low static power consumption and high noise immunity characteristic of the CD40106B family. The hermetic ceramic package and military temperature screening ensure reliable performance over the full –55 °C to +125 °C range demanded by defense and aerospace environments.

Typical applications include signal conditioning in ruggedized embedded systems, switch debouncing for cockpit or vehicle control panels, pulse shaping in timing circuits, and oscillator generation for mission-critical communication hardware. The part is regularly specified in avionics, satellite subsystems, and high-reliability industrial controls where extended temperature operation and traceability are required. From a procurement perspective, the CD40106BF3A occupies a niche military product line, and like many ceramic-encapsulated logic devices, it carries an elevated obsolescence risk as foundry support for legacy packages narrows. Engineers should verify current production status through Texas Instruments’ military lifecycle tools and source exclusively through authorized channels to preserve full lot traceability and counterfeit mitigation. Long lead times and minimum-order constraints are common, making early demand planning essential.
