Description
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.
