3.3V Fast CMOS Clock Driv er
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 reduced loading
on input clock. TTL level outputs reduce noise levels on the part.
Typical applications are clock and signal distributon

Notes:
1. For Max. or Min. conditions, use appropriate value specifi ed under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, +25°C ambient and maximum loading.
3. VOH = VCC – 0.6V at rated current.
4. This parameter is determined by device characterization but is not production tested.
5. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
