Description
The HCPL05XX, and HCPL04XX optocouplers consist of
an AlGaAs LED optically coupled to a high speed photo-
detector transistor housed in a compact 8-pin small out-
line package.
A separate connection for the bias of the photodiode
improves the speed by several orders of magnitude over
conventional phototransistor optocouplers by reducing
the base-collector capacitance of the input transistor. The
HCPL04XX devices do not have the base bonded out to
a lead for additional noise margin. The HCPL053X
devices have two channels per package for optimum
mounting density.

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes
1Current Transfer Ratio is designed as a ratio of output collector current, IO, to the forward LED input current, IF
, times
100%.
2. The 4.1 k load represents 1 LSTTL unit load of 0.36 mA and 6.1k pull-up resistor.
3. The 1.9 k load represents 1 TTL unit load of 1.6 mA and 5.6 k pull-up resistor.
4. Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge
of the common mode pulse signal VCM, to assure that the output will remain in a logic high state (i.e., VO>2.0 V).
Common mode transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge
of the common mode pulse signal, VCM, to assure that the output will remain in a logic low state (i.e., VO<0.8 V).
5. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are
shorted together.
6. 2500 VAC RMS for 1 minute duration is equivalent to 3000 VAC RMS for 1 second duration.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failedapplications,
and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technicalandproduct information.
Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide
any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
