CD40106BM

CD40106BM Description

The CD40106BM from Texas Instruments is a hex Schmitt-trigger inverter belonging to the 4000B series, designed for robust digital logic applications. Housed in a 14-pin SOIC package, this surface-mount IC integrates six independent inverters, each featuring Schmitt-trigger inputs for enhanced noise immunity and signal conditioning. Operating across a wide voltage range (3V to 18V), it delivers reliable performance in mixed-voltage environments. With a maximum propagation delay of 120ns at 15V and 50pF, it balances speed and power efficiency, making it suitable for both low-speed and medium-speed digital systems. The device is ROHS3 compliant and adheres to REACH and ECCN (EAR99) standards, ensuring environmental and regulatory compliance.

CD40106BM Features

• Schmitt-Trigger Inputs: Provides hysteresis (typically 0.9V to 4V for low-level and 3.6V to 10.8V for high-level), improving noise rejection and signal integrity.
• Low Power Consumption: Quiescent current as low as 4 µA, ideal for battery-operated or power-sensitive designs.
• High Output Drive: Capable of sourcing/sinking 3.4mA, enabling direct interfacing with TTL or CMOS loads.
• Wide Operating Voltage (3V–18V): Supports flexible power supply configurations.
• Hex Inverter Configuration: Six independent inverters in a compact 14-SOIC package, optimizing board space.
• Robust Construction: MSL 1 (Unlimited) moisture sensitivity ensures reliability in storage and assembly.

CD40106BM Applications

• Signal Conditioning: Cleans up noisy or slow-rising signals in sensor interfaces or communication systems.
• Oscillators/Waveform Generators: Used in RC-based oscillators due to Schmitt-trigger hysteresis.
• Level Shifting: Bridges logic levels between 3.3V, 5V, and higher-voltage systems.
• Debouncing Circuits: Ideal for mechanical switch or encoder input conditioning.
• Industrial Controls: Suitable for harsh environments owing to wide voltage tolerance and noise immunity.

Conclusion of CD40106BM

The CD40106BM stands out as a versatile, low-power solution for noise-immune digital logic applications. Its Schmitt-trigger inputs, wide voltage range, and compact integration make it superior to basic inverters in environments requiring signal integrity. Whether used in consumer electronics, industrial automation, or embedded systems, this IC delivers reliability, efficiency, and design flexibility. Texas Instruments' quality assurance further ensures its suitability for long-term, high-volume deployments.
