Description

The FOD250L, FOD050L and FOD053L optocouplers

consist of an AlGaAs LED optically coupled to a high

speed photodetector transistor. These devices are speci-

ﬁed for operation at a 3.3V supply voltage.

A separate connection for the bias of the photodiode

improves the speed by several orders of magnitude over

conventional

phototransistor optocouplers by reducing the base-

collector capacitance of the input transistor.

An internal noise shield provides superior common

mode rejection of CM

H

= 50kV/ms (typical) and CM

L

=

35kV/ms (typical).

Absolute Maximum Ratings

(T

A

= 25°C unless otherwise speciﬁed.)

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.
