DESCRIPTION

· The LogiSwitch LS10 Series (LS18, LS19, LS20) is a high noise immunity debounce/noise filter IC designed for severe electrically hostile environments.

· It eliminates switch bounce without requiring external components.

· Features low-impedance 25mA totem-pole outputs for each channel.

· Utilizes proprietary NoBounce™ technology for high noise immunity.

· Inputs and outputs share the same polarity, suitable for active high or active low roles.

FEATURES

· Internal pull-up resistor on each channel input.

· Compatible with SPST switches requiring only one pin (COM) tied to ground.

· Outputs delayed by Clean Time (tcltm) + Bounce Time (tbnc) on activation and release.

· Blocks noise spikes shorter than Clean Time (tcltm).

APPLICATIONS

· Suitable for toggle switches, pushbutton switches, limit switches, microswitches, and magnetic reed switches.

· Works with switches in active high or active low roles.

· Compatible with switches featuring normally open (NO) or normally closed (NC) contacts.
