These diode-transistor optocouplers use an insulating layer between a LED and an integrated photodetector to provide electrical insulation between input and output. Separate connections for the photodiode bias and out put-transistor collector increase the speed up to a hun dred times that of a conventional phototransistor coupler by reducing the base-collector capacitance.
These single channel optocouplers are available in 8-Pin DIP, SO-8 and Widebody package configurations.
The 6N135, HCPL-0500, and HCNW135 are for use in TTL/ CMOS, TTL/LSTTL or wide bandwidth analog applications. Current transfer ratio (CTR) for these devices is 7% mini mum at IF = 16 mA.
The 6N136, HCPL-2502, HCPL-0501, and HCNW136 are designed for high speed TTL/TTL applications. A standard 16 mA TTL sink current through the input LED will pro vide enough output current for 1 TTL load and a 5.6 kΩ pull-up resistor. CTR for these devices is 19% minimum at IF = 16 mA.
