PHOTOCOUPLER
PS9821-1,-2
HIGH CMR, 15 Mbps OPEN COLLECTOR OUTPUT TYPE
8-PIN SSOP (SO-8)
−NEPOC Series−
3.3 V HIGH-SPEED PHOTOCOUPLER
DESCRIPTION
The PS9821-1 and PS9821-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting diode
on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on the
output side.
The PS9821-1, -2 are designed specifically for high common mode transient immunity (CMR) and low pulse width
distortion, PS9821-2 is suitable for high density applications.

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.
USAGE CAUTIONS
1. Protect against static electricity when handling.
2. Avoid storage at a high temperature and high humidity.

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.
