Product Description
Pericom Semiconductor’s PI49FCT series of logic circuits are
produced using the Company’s advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
The PI49FCT807T and PI49FCT2807T clock drivers feature one
input and ten outputs. 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.
The PI49FCT2807T also features a 25-ohm on-chip resistor for
lower noise.

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 = 5.0V, +25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. This parameter is determined by device characterization but is not production tested.
