Description
The HCPL-2533 is a dual channel optocoupler which is
specified for use in LSTTL-to-LSTTL and TTL-to-LSTTL
logic interfaces. A nominal 8 mA LSTTL 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-2533 is 15% minimum at
IF = 8 mA.
The HCPL-2533 contains a pair of light emitting diodes
and integrated photon detectors with a 3000 Vdc
withstand test between input and output. Separate
connection for the photodiode bias and output tran-
sistor collector reduce the base-collector capacitance,
giving improved speed compared with conventional
phototransistor couplers.
