Application Notes

This brief app note explains how to identify pin 1 on the LS10 and LS100 Series NoBounce debounce ICs

The LogiSwitch LS10 Series of High Noise Immunity Debouncer/Noise Filter ICs was designed for trouble-free use in the most severe electrically hostile environments. The LS10 Series utilizes LogiSwitch’s proprietary NoBounce™ technology resulting in a high level of noise immunity. Noise spikes of less than 20 ms duration are prohibited from starting or terminating a cycle.

The LS100 line of Ultra-Fast Response Debouncer ICs provides the circuit designer with the unique LogiSwitch NoBounce™ technology adaptive debounce logic and powerful handshake protocol for carefree, bounce-free, delay-free, and poll-free operation.

DigiKey created this very thorough video to explain the basics of mechanical switch bounce and methods to eliminate switch bounce.

Switch bounce or “ringing” can cause some serious issues with connected circuitry. Logic or digital circuits view this mechanical bounce as the switch being engaged multiple times in very short succession resulting in unreliable input data. Using various external components, switch bounce can be overcome before the signal reaches data collection points. Latch and RC debounce circuits are demonstrated in this video.

Often, in noisy industrial environments, higher voltages are used to reduce signal noise. This isachieved with simple level shifting techniques. You can download the app note pdf by clicking here or...

The LogiSwitch NoBounce™ LS100 Series of debounce ICs provide an exclusive feature that dramatically speeds up switch service transactions and completely eliminates the necessity of polling for switch release to terminate the cycle.

This tutorial is to demonstrate all five methods for debouncing switches using single pole-single throw, or single pole-double throw switches. The guide includes the two methods for single pole-double throw (SPDT) switches which require no output delay and the two best methods for interfacing with the simpler single pole-single throw (SPST) switches

Eliminating the inconvenience of contact bounce is only the beginning for LogiSwitch. This section will show some of the advantages of using LogiSwitch NoBounce™ debouncer chips in modern...
