HIGH CMR, 10 Mbps OPEN COLLECTOR OUTPUT TYPE
8-PIN DIP PHOTOCOUPLER
FOR CREEPAGE DISTANCE OF 8 mm
NEC Compound Semiconductor Devices, Ltd. 2005
DESCRIPTION
The PS9687L1 and PS9687L2 are optically coupled isolators containing a GaAlAs LED on the input side and a
photo diode and a signal processing circuit on the output side on one chip.
The PS9687L1 and PS9687L2 are designed specifically for long creepage-distance as well as high common mode
transient immunity (CMR) and high speed digital output type. Consequently, they are suitable for high speed logic
interface that needs long creepage-distance (8 mm) on mounting.
The PS9687L1 is in a plastic DIP (Dual In-line Package) and the PS9687L2 is lead bending type (Gull-wing) for
surface mounting.
FEATURES
• Long creepage distance (8 mm MIN.)
• High common mode transient immunity (CMH, CML = ±20 kV/
µ
s TYP.)
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High-speed response (10 Mbps)
• Pulse width distortion (tPHL − tPLH = 15 ns TYP.)
• Open collector output
• Ordering number of tape product: PS9687L2-E3, E4: 1 000 pcs/reel
• Safety standards

PS9687L1,PS9687L2
(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.

While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as
redundancy, fire-containment, and anti-failure features.
NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor 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 semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation, NEC Compound Semiconductor Devices, Ltd.
and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
