Tel: 886-2-2222-6181 Fax: 886-2-2221-1948 / 886-2-2221-0660 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/sec TTL compatible output 0.1V V typical OL 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 1.3 Functional Diagram Truth Table (Positive Logic) LED OUT ON L OFF H A 0.1F bypass Capacitor must be connected between Pin8 and Pin5 Part No. : 6N138-L 6N139-L series BNS-OD-FC002/A4 1/15
