The single channel HCPL-2503 optocoupler is specified for use in LSTTL-to-LSTTL and TTL-to-LSTTL logic interfaces.
A nominal 8 mA sink current through the input LED will provide enough output current for proper operation of 1 LSTTL gate under worst-case conditions when used in the recommended circuits. The CTR of the HCPL-2503 is 15% minimum at IF = 8 mA.
The HCPL-2503 contains a light emitting diode and an integrated photon detector with a 3000 Vdc withstand test between input and output. Separate connection for the photodiode bias and output transistor collector reduce the base-collector capacitance, giving improved speed compared with conventional phototransistor couplers.
