DATA SHEET

PHOTOCOUPLER

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)
