Features

General Description
The FOD0708 and FOD0738 optocouplers consist of an AlGaAs LED optically coupled to a high speed transimpedance amplifier and voltage comparator. These optocouplers utilize the latest CMOS IC technology to achieve outstanding performance with very low power consumption. The devices are housed in a compact 8-pin SOIC package for optimum mounting density.

5 V CMOS compatibility 15 ns typical pulse width distortion 30 ns max. pulse width distortion 40 ns max. propagation delay skew High speed: 15 MBd 60 ns max. propagation delay 10 kV/ s minimum common mode rejection 40 C to 100 C temperature range UL approved (file E90700)

Applications

Line receivers Pulse transformer replacement Output interface to CMOS-LSTTL-TTL Wide bandwidth analog coupling
