Description
The PI6C49X0206T is a low skew, 1-to-6 LVCMOS/LVTTL
High Performance Fanout Buffer. The PI6C49X0206T has a
single ended clock input. The single ended clock input accepts
LVCMOS or LVTTL input levels. The PI6C49X0206T features a
pair of LVCMOS/LVTTL outputs. Guaranteed output and part-to-
part skew characteristics make the PI6C49X0206T ideal for clock
distribution applications demanding well defined performance
and repeatibility.

Parameters measured at f MAX unless otherwise noted.
NOTE 1: Measured from VDD /2 of the input to VDDO /2 of the output.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at VDDO /2.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load
conditions. Using the same type of inputs on each device, the outputs are measured at VDDO /2.
NOTE 4: Defined from 20% to 80%
