Description
High Speed Transistor Optocouplers
Manufacturer
Fairchild Semiconductor
Datasheet
DESCRIPTION
The FOD250L, FOD050L and FOD053L optocouplers consist of an AlGaAs LED optically coupled to a high
speed photodetector transistor. These devices are specified for operation at a 3.3V supply voltage.
A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional
phototransistor optocouplers by reducing the base-collector capacitance of the input transistor.
An internal noise shield provides superior common mode rejection of CM
FEATURES
• Low power consumption
• High speed
• Available in single channel 8-pin DIP (FOD250L), 8-pin SOIC (FOD050L) or dual channel 8-pin SOIC (FOD053L)
• Superior CMR – CM
• Guaranteed performance over temperature: 0°C to 70°C
• U.L. recognized (File # E90700)
• VDE pending
APPLICATIONS
• Line receivers
• Pulse transformer replacement
• High speed logic ground isolation: LVTTL/LVCMOS
• Wide bandwidth analog coupling
