Product Description
Pericom Semiconductor’s PI49FCT series of logic circuits are pro-
duced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The 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 outputs reduce noise levels on the part. Typical applications
are clock and signal distribution.

Notes:
1. For Max. or Min. conditions, use appropriate value specified 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.
