PS8742

DESCRIPTION

FEATURES

•

HIGH SPEED RESPONSE:

fc = 6 MHz @ 3 dB TYP

The PS8742 is an optically coupled isolator containing a

GaAIAs LED on the light emitting diode (input) side and two

photodiodes on the output side. This device is suitable for

analog high linear control applications such as PCMCIA card,

MODEM Voice telephony and FAX machines.

HIGH ISOLATION VOLTAGE:

BV: 1500 Vr.m.s.

HIGH TRANSFER GAIN LINEARITY:

∆K3 = 1% MAX

SMALL THIN PACKAGE:

16 pin SOP: 225 mil,

APPLICATIONS

Pin pitch: 1.27 mm, Height = 2.1 mm
