PHOTOCOUPLER
PS9687L1,PS9687L2
−NEPOC Series−
HIGH CMR, 10 Mbps OPEN COLLECTOR OUTPUT TYPE
8-PIN DIP PHOTOCOUPLER
FOR CREEPAGE DISTANCE OF 8 mm
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.

(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.
