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
• 40% reduction of mounting area (5-pin SOP × 2) • Low power consumption (VCC = 3.3 V) • High isolation voltage (BV = 2 500 Vr.m.s.) • High-speed response (tPHL = 0.6 µs MAX., tPLH = 0.9 µs MAX.) • Ordering number of tape product: PS8821-1-F3, F4: 1 500 pcs/reel : PS8821-2-F3, F4: 1 500 pcs/reel • Pb-Free product

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.
