3.3V Fast CMOS Clock Driver
Description
Pericom Semiconductor's PI49FCT3807 is a 3.3V 1-to-10 clock
driver. This low skew clock driver features one input and ten outputs
fanout. The large fanout from a single input line reduces loading
on input clock. TTL level ouputs reduce noise levels on the part.
Typical applications are clock and signal distribution.

Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional operation
of the device at these or any other conditions above those
indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.
