PS8701
HIGH NOISE REDUCTION HIGH-SPEED ANALOG OUTPUT TYPE
5-PIN SOP PHOTOCOUPLER
DESCRIPTION
The PS8701 is an optically coupled isolator 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.
This is a plastic SOP (Small Out-line Package) type for high density applications.
FEATURES
•High common mode transient immunity (CMH, CML = ±10 kV/μs MIN.)
•High supply voltage (VCC = 35 V)
•High isolation voltage (BV = 2 500 Vr.m.s.)
•High-speed response (tPHL = 0.8 μs MAX., tPLH = 1.2 μs MAX.)
•Taping product number (PS8701-E3, E4, F3, F4)
APPLICATIONS
•Computer and peripheral manufactures
•General purpose inverter
•Substitutions for relays and pulse transformers
•Power supply
