NTE NTE3095

NTE3095
Optoisolator
Description:
The NTE3095 is a dual photocoupler optoisolator in an 8–Lead DIP type package consisting of a pair
of Gallium Aluminum Arsenide light emitting diodes and integrated photodetectors. Separate connections for the photodiode bias and output transistor collectors improve the speed up to a hundred
times that of a conventional phototransistor coupler by reducing the base–collector capacitance.

Note 7. Common mode transient immunity in Logic High level is the maximum tolerable (positive)
dVcm/dt on the leading edge of the common mode pulse, Vcm, to assure that the output will
remain in a Logic High state (i.e., VO > 2V). Common mode transient immunity in Logic Low
level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode
pulse signal, Vcm, to assure that the output will remain in a Logic Low state (i.e., VO > 0.8V).
Note 8. The frequency at which the AC output voltage is 3dB below the low frequency asymptote.
