DESCRIPTION
NEC's 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 specifi cally 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 F is used between V
CC
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 fl ux with freon-based and chlorine-basee="position:absolute;top:136;left:116">Avoid removing the residual fl ux 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.
