High Speed Photo Darlington Transistor Coupler, DIP8, Viso=5000Vrms, DC Input, 1 Channel, CRT Min.400%, Typ.2600%, CMR=1000V/μs, Black Case, Max.45pcs/tube
DESCRIPTION:
The 6N139 series combines an AlGaAs infrared emitting diode as the emitter which is optically coupled to a silicon high speed photo Darlington transistor in a plastic DIP8 package with different lead forming options. A separate design between photodiode and Darlington transistor reduces the base-collector capacitance of the input transistor which improves the speed by several orders of magnitude over conventional phototransistor opto-couplers.
APPLICATIONS:
· Low current line receivers
· Current loop receivers
· Out interface to CMOS-LSTTL-TTL
· Pulse transformer replacement
· Computer-peripheral interface
