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 (t

USAGE CAUTIONS

1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static
electricity when handling.

2. By-pase capacitor of more than 0.1 µF is used between VCC and GND near device.
