Key Features

  • Six independent Schmitt-trigger inverters with built-in hysteresis providing noise immunity for slow or noisy input signals
  • 4000/14000/40000 CMOS family with wide supply voltage range enabling operation in both 3.3V and 5V and 12V logic systems
  • 400ns propagation delay in a through-hole 14-pin DIP package ideal for prototyping, repair, and legacy system maintenance
  • Simple single-input inverter architecture allowing use as oscillator, pulse shaper, debounce circuit, or level translator

Applications

The CD40106BCN is commonly used as a relaxation oscillator by connecting a resistor-capacitor network between its output and input, generating square waves for timing and clock generation in hobby and industrial circuits. Its Schmitt-trigger inputs make it ideal for conditioning slow-slewing or noisy signals from sensors, switches, and long cable runs before feeding into digital logic. It is also widely used in educational electronics, prototyping boards, and legacy system repairs where 4000-series CMOS compatibility is required.

Frequently Asked Questions

What is the CD40106BCN and how many inverters does it contain?

The CD40106BCN is a hex Schmitt-trigger inverter IC containing six independent CMOS inverters, each with a single input and single output, housed in a 14-pin DIP package as part of the 4000-series CMOS logic family.

What is the propagation delay of the CD40106BCN?

The CD40106BCN has a propagation delay (tpd) of 400ns, which is typical for 4000-series CMOS logic. This is adequate for low-frequency logic conditioning, oscillators, and signal-shaping applications but not for high-speed digital buses.

What package does the CD40106BCN come in?

The CD40106BCN is packaged in a 14-pin rectangular plastic DIP (Dual In-line Package), making it easy to insert into breadboards and through-hole PCBs for rapid prototyping, repair work, and educational electronics projects.

Can the CD40106BCN be used as an oscillator?

Yes, each Schmitt-trigger inverter in the CD40106BCN can form a relaxation oscillator by connecting a resistor between output and input and a capacitor from input to ground. This is a widely used technique for generating square waves in timing and clock circuits.

Is the CD40106BCN still in active production?

The CD40106BCN has a YTEOL of 0, indicating it may be approaching or at end-of-life status. Designers starting new projects should verify current availability and consider migrating to active 4000-series equivalents or modern Schmitt-trigger logic ICs for long-term supply assurance.
