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 V
OL
typical
UL, CSA approved.
1.2 Applications
