Description
The 6N135, 6N136, CT4502 and CT4503 devices each consist of an infrared emitting diode, optically coupled to a high speed photo detector transistor. A separate connection for the photodiode bias and output-transistor collector increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor.

Features
• High speed 1MBit/s
• High isolation voltage between input and output
   (Viso=5000 Vrms )
• Guaranteed CTR performance from 0°C to 70°C
• Wide operating temperature range of -55°C to
   100°C
• Regulatory Approvals
   ■ UL - UL1577 (E364000)
   ■ VDE - EN60747-5-5(VDE0884-5)
   ■ CQC – GB4943.1, GB8898
   ■ IEC60065, IEC60950

Applications
• Line receivers
