HIGH-SPEED PHOTOCOUPLER
−NEPOC Series−
DESCRIPTION
The PS9122 is an optical coupled high-speed, active low type isolator containing a GaAlAs LED on the input side
and a photodiode and a signal processing circuit on the output side on one chip.
The PS9122 is a high-speed digital output type photocoupler designed specifically for low circuit current.
The PS9122 is in 5-pin plastic SOP (Small Outline Package) and is suitable for high density application.

*1, 5. Typical values at TA = 25°C
*2, 6. Because VOL of 2 V or more may be output when LED current input and when output supply of VCC = 2 V
more or less, it is important to confirm the characteristics (operation with the power supply on and off) during
design, before using this device.

USAGE CAUTIONS
1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static
electricity when handling.
2. By-pass capacitor of 0.1 μF is used between VCC and GND near device. Also, ensure that the distance between
the leads of the photocoupler and capacitor is no more than 10 mm.
3. Avoid storage at a high temperature and high humidity.

(4) Cautions
• Fluxes
Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between
collector-emitters at startup, the output transistor may enter the on state, even if the voltage is within the absolute
maximum ratings.

•
NEC Electronics products are classified into the following three quality grades: "Standard", "Special" and
"Specific".
The "Specific" quality grade applies only to NEC Electronics products developed based on a customer-
designated "quality assurance program" for a specific application. The recommended applications of an NEC
Electronics product depend on its quality grade, as indicated below. Customers must check the quality grade of
each NEC Electronics product before using it in a particular application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots.
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support).
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC Electronics products is "Standard" unless otherwise expressly specified in NEC
Electronics data sheets or data books, etc. If customers wish to use NEC Electronics products in applications
not intended by NEC Electronics, they must contact an NEC Electronics sales representative in advance to
determine NEC Electronics' willingness to support a given application.
(Note)
(1)
"NEC Electronics" as used in this statement means NEC Electronics Corporation and also includes its
majority-owned subsidiaries.
(2)
"NEC Electronics products" means any product developed or manufactured by or for NEC Electronics (as
defined above).
