Product details

Single Schmitt-trigger buffer — noise-tolerant signal conditioning

The Schmitt-trigger input provides hysteresis that cleans up slow or noisy edges — useful for interfacing with mechanical switches, RC-oscillator signals, or long PCB traces where ringing is a concern. Output drive is rated 32 mA source and sink, enough to drive LED indicators, relay coils through a transistor, or multiple CMOS logic inputs.

TI has discontinued this specific suffix variant. Buyers should expect to work with surplus or new-old-stock inventory — date-code spread and reel condition vary by lot, so sealed factory reels with consistent date-codes are the preferred procurement target.

SC-70-5 footprint — board-area efficient

The SN74LVC1G17DCKJ is supplied in a 5-pin SC-70-5 package (also known as SOT-353). The supplier device package is SC-70-5, a very small surface-mount footprint that saves board space in dense designs.

Frequently asked questions

What is the replacement for SN74LVC1G17DCKJ?

The closest pin-compatible alternative within the same 74LVC1G17 function is the SN74LVC1G17DCKR, which shares the same die and electrical characteristics but differs in packaging suffix. The SN74LVC1G17DCKJ uses the DCKJ suffix; the DCKR variant may still be active. Verify the exact package and ordering code against your BOM.

Is SN74LVC1G17DCKJ RoHS compliant?

The record does not explicitly state RoHS compliance status. Standard TI 74LVC devices from this era are typically RoHS-compliant unless marked otherwise, but the buyer should verify against the specific date-code lot at quote time.
