6N137SM

Overview

The onsemi 6N137SM is a high-speed logic gate optocoupler featuring an 850 nm AlGaAs LED coupled to an integrated photo-detector with a strobable output. It operates at data rates up to 10 Mb/s and provides an open collector output for wired OR configurations. The device offers superior common mode rejection of typically 10 kV/µs and supports fan-out of 8 over the temperature range of -40°C to +85°C. Key electrical parameters include a forward current of 10 mA, forward voltage of 1.4 V, rise time of 30 ns, fall time of 10 ns, and isolation voltage of 5000 Vrms.

Feature Summary

• Features a strobable output with open collector configuration enabling wired OR connections.
• Provides superior common mode rejection of typically 10 kV/µs via internal noise shielding.
• Integrates an 850 nm AlGaAs LED with a high-speed integrated photo-detector logic gate.

Applications

• Ground loop elimination
• LSTTL to TTL or 5 V CMOS interfacing
• Line receiver and data transmission systems
• Switching power supplies
• Computer-peripheral interfaces

Procurement Notes

Verify the specific suffix 'SM' confirms the surface mount gull-wing package variant rather than through-hole DIP versions like 'VM'. Confirm RoHS status and lead-free compliance in the official datasheet before procurement. Ensure supply chain sources provide valid manufacturer documentation to distinguish from generic equivalents.

Selection Notes

Select this component when high-speed digital isolation exceeding 10 Mb/s is required alongside robust noise immunity. The open collector output allows flexible logic interfacing and wired OR capabilities. Verify that the 5000 Vrms isolation rating meets safety standards for the target application environment.
