Description
Product Overview
The CD40106BE from Texas Instruments is a CMOS hex Schmitt‑trigger inverter designed for demanding industrial and scientific applications. Each package contains six independent inverting gates, each featuring built‑in hysteresis that provides superior noise rejection and clean signal transitions. The device operates over a wide supply voltage range from 5 V to 15 V, making it adaptable to both low‑voltage logic families and higher‑voltage control circuits. With a typical hysteresis voltage of 0.9 V at 5 V supply, 2.3 V at 10 V, and 3.5 V at 15 V, the CD40106BE ensures that noisy or slowly changing inputs are reliably converted to crisp digital outputs.
Key specifications include a maximum input current of 1 µA at 18 V, a quiescent current of less than 100 nA at 18 V and 25 °C, and a guaranteed low VDD and VSS current even during slow input ramps. The device tolerates any input rise or fall time, eliminating the need for external timing components in many designs. Packaged in a standard 16‑pin DIP or SOIC format, the CD40106BE is supplied in a convenient pack of 20, providing ample inventory for production runs and prototyping projects.

Usage
Engineers and designers frequently employ the CD40106BE in environments where signal integrity is critical. Typical use cases include debounce circuits for mechanical switches, waveform shaping for pulse‑width modulation, and level‑shifting between different logic families. Its robust noise immunity makes it ideal for automotive sensor interfaces, industrial control panels, and laboratory instrumentation where electromagnetic interference is common.
Because the inverter tolerates a wide range of input rise and fall times, it can be used directly with slow‑moving sensors such as thermistors, photoresistors, and capacitive touch elements without additional buffering. The low power consumption enables battery‑powered devices to operate for extended periods, while the high noise immunity ensures reliable operation in harsh environments like factories, outdoor installations, and aerospace test rigs.
When integrating the CD40106BE into a PCB layout, keep the supply pins decoupled with a 0.1 µF ceramic capacitor placed close to the VDD pin. This simple step further improves transient response and reduces the likelihood of supply‑induced glitches. The device’s symmetrical output characteristics also simplify board routing, as each gate can drive both high‑side and low‑side loads without additional level‑shifting components.
