Description

The FODM452 and FODM453 optocouplers consist of

an AlGaAs LED optically coupled to a high speed photo-

detector transistor. The devices are housed in a compact

5-pin mini flat package for optimum mounting density.

The FODM453 features a high CMR rating for optimum

common mode transient immunity.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

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) 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).
