Description
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 output-transistor collector increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base-collector capacitance.

* NOTE: FOR 4502/3, 0452/3, PIN 7 IS NOT CONNECTED.
A 0.1 µF bypass capacitor must be connected between pins 5 and 8.
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.

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% minimum 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 provide 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. The HCPL-4502, HCPL-0452, and HCNW4502 provide the electrical and switching performance of the 6N136, HCPL-0501, and HCNW136 with increased ESD protection. The HCPL-4503, HCPL-0453, and HCNW4503 are similar to the HCPL-4502, HCPL-0452, and HCNW4502 optocouplers but have increased common mode transient immunity of 15 kV/µs minimum at VCM = 1500 V guaranteed.
