Description
The PI6C185-00 is a high-speed low-noise 1-7 non-inverting
buffer designed for SDRAM clock buffer applications.
This buffer is intended to be used with the PI6C10X clock genera-
tor for Intel Architecture-based Mobile systems.
At power up all SDRAM output are enabled and active. The I

C
Serial control may be used to individually activate/deactivate any
of the 7 output drivers.
Note:
Purchase of I
