FODM453R2 Datasheet, PDF (5/14 Pages) Fairchild Semiconductor – 5-Pin Mini Flat Package High Speed Transistor Optocoupler

Notes:
1. Current Transfer Ratio is defined as a ratio of output collector current, I_O, to the forward LED input current, I_F,
times 100%.
2. The 1.9kΩ load represents 1 TTL unit load of 1.6mA and 5.6kΩ pull-up resistor.
3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV_cm/dt on the
leading edge of the common mode pulse signal V_CM, to assure that the output will remain in a logic high state
(i.e., V_O > 2.0V). Common mode transient immunity in logic low level is the maximum tolerable (negative) dV_cm/dt
on the trailing edge of the common mode pulse signal, V_CM, to assure that the output will remain in a logic low
state (i.e., V_O < 0.8V).
4. Device is considered a two terminal device: Pins 1, and 3 are shorted together and Pins 4, 5, and 6 are shorted
together.
