Description
The 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 rec-
ommended circuits. The CTR of the HCPL-2503 is 15%
minimum at I_F = 8 mA.
The HCPL-2503 contains a light emitting diode and an in-
tegrated 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.
