6N137S-TA1-L

6N137S-TA1-L is a Lite-On single-channel high-speed logic optocoupler in an SMD-8 gull-wing package — 5,000 Vrms isolation, 15 MBd typical data rate and 10 kV/µs minimum common-mode rejection, on 2.7 V to 3.6 V or 4.5 V to 5.5 V supplies with 20 mA maximum input current, over −40 to +85 °C, for isolated logic and high-speed interface duty in the long-running 6N137 socket. Selection advice: the full string is assembled from the naming rule in Lite-On's 6N137-L series datasheet (S = surface-mount, TA1 = tape direction, -L = series suffix) — Lite-On publishes no standalone product page for this code, and its evidence base is the current series datasheet plus authorized distributor listings carrying the full code as Active, so insist on the complete string rather than a bare 6N137, whose makers and speed grades vary widely. Parameters verified against Lite-On documentation.
