Photocoupler
6N138-L 6N139-L series
1. DESCRIPTION
These high gain series couplers use a light emitter diode and an integrated high gain photo detector to provide extremely high
current transfer ratio between input and output. Separate pins for the photodiode and output stage result in TTL compatible saturation
voltage and high speed operation. Where desired the Vcc and Vo terminals may be tied together to achieve conventional photo
Darlington operation. A base access terminal allows a gain bandwidth adjustment to be made.
1.1 Features
High current transfer ratio – 2000% typical.
Low input current requirements – 0.5mA
High output current – 60mA
CTR guarantee – 0~70℃.
Instantaneous common mode rejection 10KV/μsec
TTL compatible output – 0.1V VOL typical
UL, CSA approved.
1.2 Applications
Digital logic ground isolation
Low input current line receiver
Telephone ring detector
EIA-RS-232C line receiver
Current loop receiver
High common mode noise line receiver

Notes
1. AC For 1 Minute, R.H. = 40 ~ 60%. Isolation voltage shall be measured using the following method.
(1) Short between anode and cathode on the primary side and between collector and emitter on the secondary
side.
(2) The isolation voltage tester with zero-cross circuit shall be used.
(3) The waveform of applied voltage shall be a sine wave.

3. Current Transfer Ratio (CTR) is defined as the ration of output collector current, Io, to the forward LED input
current, IF, times 100%.
4. Pin 7 open.
5. Instantaneous common mode rejection voltage "output (1)" represents a common mode voltage variation that can hold
the output above (1) level (Vo>2.0V).Instantaneous common mode rejection voltage "output (0)" represents a common
mode voltage
variation that can hold the output above (0) level (Vo
