PHOTOCOUPLER
PS8821-1,-2
1 Mbps ANALOG OUTPUT TYPE
8-PIN SSOP (SO-8)
HIGH-SPEED PHOTOCOUPLER
? NEPOC Series ?
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.
FEATURES
? 40% reduction of mounting area (5-pin SOP × 2)
? Low power consumption (V CC = 3.3 V)
? High isolation voltage (BV = 2 500 Vr.m.s.)
? High-speed response (t PHL = 0.6 μ s MAX., t PLH = 0.9 μ s MAX.)
