LogiSwitch LS119-P

LS119-P is the six-channel through-hole member of the LS100 switch-debouncer family. Its adaptive NoBounce circuitry rejects mechanical contact bounce without an external RC timing network. Normally low output/handshake pins can report switch events to a host and accept acknowledgement pulses when the handshake mode is used.

The LS119-P suffix identifies a 14-pin PDIP, 300 mil wide, matching LCDChip's registered 14-DIP package name. This through-hole outline is mechanically different from the 150 mil narrow SOIC LS119-S variant.

Layout checks

• Use the manufacturer's controlled package dimensions for hole pitch and row spacing.
• Verify pin-1 orientation before assigning supply and switch nets.
• Do not reuse the LS119-S SOIC land pattern for this PDIP.

The registered local 14-DIP JPG is missing. The expected public path remains reserved pending artwork; do not rely on the illustration for mechanical design.

The LS119 pin-description table identifies these functions for both package variants. Its name column repeats “SW0” for pins 5–7 even though the function column describes switch inputs 3–5. Obtain manufacturer clarification before assigning final signal names.

The repeated pin names are a source-document discrepancy, not an inferred pinout correction.

Confirm the manufacturer's applicable temperature and timing test conditions, and resolve the pin-name discrepancy before qualification.

LS119-S is the manufacturer-listed six-channel LS119 SOIC member and exists in the LCDChip catalog, but its 150 mil surface-mount footprint differs from the LS119-P 300 mil through-hole PDIP. LS19-P is another 14-pin PDIP switch debouncer from the LS10 family; verify its lack of the same handshake behavior, operating range and timing before considering a redesign. Neither part is presented as a confirmed drop-in replacement.

LogiSwitch lists LS119-P as the six-channel PDIP variant of its LS100 NoBounce family with handshake. The LS100 Series IC User's Guide supplies the package, pin functions and electrical data summarized here; the pin-name discrepancy should be clarified with LogiSwitch.

Verify the exact LS119-P order code, package marking, supplier traceability and pin-1 indication on receipt. Confirm the 14-DIP body and current manufacturer guide before assembly; obtain lot and compliance records from the supplier where required.

This summary does not replace the controlled manufacturer guide. Resolve the pins 5–7 naming discrepancy, verify supply and timing conditions, and confirm the 300 mil PDIP mechanical drawing before design release or substitution. The registered package JPG is not yet available.
