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.
