LogiSwitch, LLC Specialized ICs LS19-S

The LS19-S is a specialized debouncer/noise filter integrated circuit designed for high noise immunity in electrically hostile environments. It features six channels with low-impedance totem-pole outputs capable of sourcing 25 mA. The device operates within a supply voltage range of +2.3 V to +5.5 V and includes internal pull-up resistors for each input, simplifying the connection to normally open switch interfaces. Utilizing LogiSwitch's proprietary NoBounce,Ñ¢ technology, the LS19-S effectively rejects noise spikes of less than 20 ms duration, ensuring reliable operation without false triggering. Each output is delayed for a period of 20 ms plus the bounce time on both activation and release, providing consistent performance. The device is suitable for applications requiring robust debounce functionality in challenging conditions.
