FOD050L, FOD250L: Single Channel
FOD053L: Dual Channel
LVTTL/LVCMOS 3.3V High Speed Transistor Optocouplers
Features
Description
■ Low power consumption
The FOD250L, FOD050L and FOD053L optocouplers
consist of an AlGaAs LED optically coupled to a high
speed photodetector transistor. These devices are specified for operation at a 3.3V supply voltage.
■ High speed
■ Available in single channel 8-pin DIP (FOD250L),
■
■
■
■
8-pin SOIC (FOD050L) or dual channel 8-pin SOIC
(FOD053L)
Superior CMR – CMH = 50kV/µs (typical) and
CML = 35kV/µs (typical)
Guaranteed performance over temperature:
0°C to 70°C
U.L. recognized (File # E90700)
VDE pending
A separate connection for the bias of the photodiode
improves the speed by several orders of magnitude over
conventional
phototransistor optocouplers by reducing the basecollector capacitance of the input transistor.
An internal noise shield provides superior common
mode rejection of CMH = 50kV/ms (typical) and CML =
35kV/ms (typical).
Applications
■ Line receivers
■ Pulse transformer replacement
■ High speed logic ground isolation: LVTTL/LVCMOS
■ Wide bandwidth analog coupling

Absolute Maximum Ratings
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:
2. The 1.9kΩ load represents 1 TTL unit load of 1.6mA and 5.6kΩ pull-up resistor.
3. The 4.1kΩ load represents 1 LSTTL unit load of 0.36mA and 6.1kΩ 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 > 2.0V). 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 < 0.8V).
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.

WHICH COVERS THESE PRODUCTS.
LIFE SUPPORT POLICY
FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used herein:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the body or (b) support or sustain life,
and (c) whose failure to perform when properly used in accordance
with instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.
2. A critical component in any component of a life support, device, or
system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its
safety or effectiveness.
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, failed applications,
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 technical and product 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.
