6N138,6N139
Current Loop Driver Low Input Current Line Receiver CMOS Logic Interface
The TOSHIBA 6N138 and 6N139 consists of a GaAℓAs infrared emitting diode coupled with a split-Darlington output configuration. A high speed GaAℓAs Ired manufactured with an unique LPE junction, has the virtue of fast rise and fall time at low drive current. • Isolation voltage: 2500 Vrms (min) • Current transfer ratio
: 6N138 − 300% (min) (IF=1.6mA) : 6N139 − 400% (min) (IF=0.5mA) • Switching time: 6N138 − tPHL = 10μs (max)
− tPLH = 35μs (max) 6N139 − tPHL = 1μs (max)
− tPLH = 7μs (max) • UL recognized: UL1577, file no. E67349

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc.).
