Overview
The 6N137-300E is a high Common Mode Rejection (CMR) and high-speed optocoupler produced by Broadcom Limited. This component combines a GaAsP light-emitting diode (LED) and an integrated high-gain photo detector. It features an enable input that allows the detector to be strobed, and the output of the detector IC is an open collector Schottky-clamped transistor. The internal shield of the 6N137-300E provides a guaranteed common mode transient immunity specification up to 15,000 V/μs at Vcm = 1000V, ensuring maximum AC and DC circuit isolation while achieving TTL compatibility. The optocoupler's operational parameters are guaranteed from -40°C to +85°C, ensuring trouble-free system performance across a wide temperature range.
