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/s (typical) and CML = 35kV/s (typical) Guaranteed performance over temperature: 0C to 70C U.L. recognized (File # E90700) VDE pending
Applications
Line receivers Pulse transformer replacement High speed logic ground isolation: LVTTL/LVCMOS Wide bandwidth analog coupling

Notes: 2. The 1.9k load represents 1 TTL unit load of 1.6mA and 5.6k pull-up resistor. 3. The 4.1k load represents 1 LSTTL unit load of 0.36mA and 6.1k pull-up resistor. 4. Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge of the common mode pulse signal VCM, to assure that the output will remain in a logic high state (i.e., VO > 2.0V). Common mode transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a logic low state (i.e., VO < 0.8V). 5. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted together.
