FOD050L, FOD250L, FOD053L LVTTL/LVCMOS 3.3V High Speed Transistor Optocouplers October 2006 FOD050L, FOD250L: Single Channel FOD053L: Dual Channel LVTTL/LVCMOS 3.3V High Speed Transistor Optocouplers Features ■ Low power consumption ■ High speed ■ Available in single channel 8-pin DIP (FOD250L), 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 CMH = 50kV/ms (typical) and CML = 35kV/ms (typical). ■ ■ ■ ■ 8-pin SOIC (FOD050L) or dual channel 8-pin SOIC (FOD053L) Superior CMR – CMH = 50kV/µs (typical) and CML = 35kV/µs (typical) 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 Schematic N/C 1 8 VCC + 1 V F1 8 VCC 8 1 + 2 VF _ 3 7 VB _ 2 7 V01 8 8 1 1 6 VO _ V 3 6 V02 F2 N/C 4 5 GND + 4 5 GND FOD050L, FOD250L FOD053L Truth Table LED On Off VO LOW HIGH ©2002 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FOD...
