It contains six independent Schmitt-trigger inverters in a 14-pin SOIC package. Each inverter has different switching thresholds for positive-going and negative-going input signals, providing hysteresis that makes the device immune to noise and oscillation on slowly-slewing input signals. The wide 3V to 15V supply range and >50% noise immunity make it suitable for both standard logic applications and demanding industrial environments. Input clamp diodes allow interfacing to voltages above VDD using current-limiting resistors. The device is fully static, consuming minimal power in the quiescent state. It is pin-compatible with the CD40106B from TI and MC140106B from onsemi, providing a multi-sourced solution for Schmitt-trigger inversion.","working_principle":"Each of the six Schmitt-trigger inverter channels has two switching thresholds: VP (positive-going, upper threshold) and VN (negative-going, lower threshold), with VP > VN. The hysteresis VH = VP - VN is typically 0.9V at VDD=5V. When the input rises through VP, the output switches low (Y = \u0100). When the input falls through VN, the output switches high. Between VP and VN, the output holds its previous state \u2014 this is the hysteresis effect. This prevents the output from oscillating when the input is near the threshold, a common problem with standard CMOS inverters driven by slow or noisy signals. The positive feedback within the Schmitt trigger creates the hysteresis: when the output begins to transition, it reinforces the input change, making the switching decisive. The CMOS output stage swings rail-to-rail (0V to VDD) with symmetrical source\/sink capability.","pin_description":"

      • Switch Debounce:<\/b> Connect a mechanical switch from VDD to the input of one channel through a pull-down resistor. The Schmitt hysteresis (0.9V at 5V) rejects the contact bounce noise, producing a clean single-edge transition at the output. With a 10k\u03a9 pull-down and 100nF input capacitor, the RC time constant filters the bounce while the Schmitt trigger squares the filtered signal. The remaining five channels can debounce additional switches.<\/li>
      • RC Relaxation Oscillator:<\/b> Create a simple clock by connecting one channel's output to its input through a resistor (R), with a capacitor (C) from input to VSS. The capacitor charges through R until reaching VP, then the output goes low and C discharges through R to VN, then the cycle repeats. At VDD=10V, R=100k\u03a9, C=10nF: f \u2248 1\/(RC\u00d7ln((VDD-VN)\/VP)) \u2248 600Hz.<\/li>
      • Sensor Signal Conditioning:<\/b> Clean up noisy sensor outputs (thermistors, photodiodes, Hall sensors) by feeding them through a voltage divider to one channel's input. The Schmitt hysteresis ensures the output transitions decisively when the sensor crosses the threshold, ignoring small fluctuations. Multiple channels can condition multiple sensor signals in a single 14-pin IC.<\/li><\/ul>","alternative_models":"
