PS8821-1

www.DataSheet4U.com DATA SHEET 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.)
