Easy method to use low-cost resistor networks to scale switch input voltage to LogiSwitch NoBounce™ ICs.

Debounce High Voltage Inputs with LogiSwitch NoBounce ICs

LogiSwitch NoBounce IC Application Examples

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 applications. The LogiSwitch Handshake feature brings a new dimension to switch service processing.

Please note that some of the real-time advantages shown in these applications are only possible with the unique LogiSwitch handshake protocol. Use of the handshake protocol is covered in detail in the IC User Guide and the Bounce-Free Switch User Guide.

The Five Basic Methods for Eliminating Switch Bounce

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

LogiSwitch NoBounce Handshake Protocol for Ultra-Fast Ultra-Simple Coding

The LogiSwitch NoBounce™ switches and the 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.

LogiSwitch NoBounce Switches with Handshake Users Guide

LogiSwitch provides a series of pushbutton and limit switches incorporating the same unique NoBounce™ adaptive debounce algorithm and handshake protocol as implemented in the LogiSwitch LS100 series line of bounce-free ICs.

All LogiSwitch switch products provide a selection of three different output formats:

  1. Normally Low/Handshake (NL/HS) pin provides an active-high handshakeable output.
  2. Normally High (NH) pin provides a low-impedance active-low output.
  3. Toggle (TG) pin changes state each time the switch is actuated. (powers-up high)
