DESCRIPTION
The
66088
single/dual optocouplers utilize infrared LEDs optically coupled to high gain photon detectors. These unique
optocouplers provide high CTR and low leakage current. The 66088 optocouplers are available in military temperature range
and military temperature with 100% device screening. The devices are built in an 8 pin hermetic, side-brazed package and
provide high input to output isolation (1500Vdc minimum).
