PHOTOCOUPLER
PS8821-1,-2
1 Mbps ANALOG OUTPUT TYPE 8-PIN SSOP (SO-8) HIGH-SPEED PHOTOCOUPLER
DESCRIPTION
The PS8821-1, -2 are optically coupled isolators containing a GaAlAs LED on the light emitting diode (input side) and a PIN photodiode and a high-speed amplifier transistor on the output side on one chip. The PS8821-2 is suitable for high density applications. -NEPOC Series-
FEATURES

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 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.
