■ Data multiplexing
Features
■ Switching power supplies
■ Compact SO8 package (except FOD260L – 8-pin DIP)
■ Pulse transformer replacement
■ Very high speed – 10 MBit/s
■ Computer-peripheral interface
■ Superior CMR — 50 kV/µs at 2,000V peak
■ Fan-out of 8 over -40°C to +85°C
Description
■ Logic gate output
These optocouplers consist of an AlGaAS LED, optically cou-
pled to a very high speed integrated photo-detector logic gate.
Single channel devices include a strobable output. This output
features an open collector, thereby permitting wired OR outputs.
The output consists of bipolar transistors in a Bi-CMOS process
for reduced power consumption. The coupled parameters are
guaranteed over the temperature range of -40°C to +85°C. A
maximum input signal of 5 mA (3 mA for the FODX6XL ver-
sions) will provide a minimum output sink current of 13 mA (fan
out of 8). An internal noise shield provides superior common
mode rejection of typically 50 kV/µs at 2,000V common mode.
■ Strobable output (single channel devices)
■ Wired OR-open collector
■ U.L. recognized (File # E90700) (pending)
■ UDE approval pending
Applications
■ Ground loop elimination
■ LSTTL to TTL, LSTTL or 5-volt CMOS
■ Line receiver, data transmission
