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/µs 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 VCC and

VO terminals may be tied together to achieve conventional photodarlington operation. A base access

terminal allows a gain bandwidth adjustment to be made.

Features:

D High Current Transfer Ratio

Note 1. The small junction sizes inherent to the design of this bipolar component increases the

component’s 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.
