Reliable Isolation and Minimized System

Realize increased design margins and stable parameters in high temperature

totransistor optocoupler. You’ll achieve high noise immunity and reliable isolation

at high operating temperatures, up to 125°C, as this new series implements

tion, the FODM8801 offers excellent CTR linearity and operates at a very low

input current (I

(AlGaAs) infrared light emitting diode optically coupled to a phototransistor.

Because the FODM8801 is packaged in a compact, half-pitch, mini-flat, 4-pin

package (1.27mm lead pitch), benefits also include board space savings and

design flexibility, ultimately allowing for overall reductions in system cost.
