•
WIDE OPERATING VCC RANGE:
VCC = -0.5 to +15 V
NEC's PS8703 is an optically coupled isolator containing a
GaAIAsLEDonthe inputsideandaPINphotodiodeandahigh
speed amplifier transistor on the output side. This is a plastic
SOP (Small Outline Package) type for high density applica-
tions.
HIGH ISOLATION VOLTAGE:
BV: 2500 Vr.m.s.
HIGH-SPEED RESPONSE:
tPHL, tPLH = 5 µs MAX (@RL = 4.1 kΩ)
