74FCT3807S DATASHEET
External Components
A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01µF should be
connected between VDD pins and GND pins, as close to the device as possible. A 33 series terminating resistor may be used
on each clock output if the trace is longer than 1 inch.
To achieve the low output skew that the 74FCT3807S is capable of, careful attention must be paid to board layout. Essentially,
all ten outputs must have identical terminations, identical loads and identical trace geometries. If they do not, the output skew
will be degraded. For example, using a 30 series termination on one output (with 33 on the others) will cause at least 15 ps
of skew.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 74FCT3807S. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the
recommended operating temperature range.
