Description
The PI6C184 is a high-speed low-noise 1-13 non-inverting
buffer designed for SDRAM clock buffer applications.
This buffer is intended to be used with the PI6C104 clock generator
for Intel Architecture for both desktop and mobile systems.
At power-up, all SDRAM outputs are enabled and active. The I²C
Serial control may be used to individually activate/deactivate any
of the 13 output drivers.
Note:
Purchase of I²C components from Pericom conveys a license to
use them in an I²C system as defined by Philips®.
