FODM452, FODM453 — 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.
