NTE3093
Optoisolator
NPN Split Darlington Output
Description:
The NTE3093 coupler uses a light emitting diode (LED) and an integrated high gain photon detector
to provide 3000V DC electrical insulation, 500V/碌s common mode transient immunity and extremely
high current transfer ratio between inut and output. Separate pins for the photodiode and output stage
result in TTL compatible saturation voltages and high speed operation. Where desired, the V
CC
and
V
O
terminals may be tied together to achieve conventional photodarlington operation. A base access
terminal allows a gain bandwidth adjustment to be made.

Note 1. The small junction sizes inherent to the design of this bipolar component increases the
component鈥檚 susceptibility to damage from electrostatic discharge (ESD). It is advised
that normal static precautions be taken in handling and assembly of this component to pre-
vent damage and/or degredation which may be induced by ESD.
