HCPL-2503
Single Channel, High Speed Logic Interface Optocoupler
Data Sheet
Lead (Pb) Free
RoHS 6 fully

RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
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 IF = 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.

Recommended Operation
The HCPL-2503 optocoupler is specified for use in LSTTL-
to-LSTTL and TTL-to-LSTTL interfaces. The recommended
circuits show the interface design and give suggested
component values. The input current IF is given as both
a nominal value and a range. The range in IF results
from the tolerances in VCC and the input resistor RIN.
The CTR of the optocoupler is given as the minimum
initial value over temperature, taken directly from the
Electrical Specifications. The value given for IOL (min) is
based on the minimum CTR and the minimum IF using
worst case values for RL and VCC. The resulting IOL (min)
has ample design margin, allowing more than 20% for
CTR degradation even under these worst case condi-
tions. For additional information on CTR degradation
see Application Note 1002.
