Description
The PI6C185-01 is a high-speed low-noise 1-5 non-inverting buffer
designed for SDRAM clock buffer applications.
This buffer is intended to be used with the PI6C10X clock generator
for Intel Architecture-based 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 5 output drivers.
Note:
Purchase of I2C components from Pericom conveys a license to
use them in an I2C system as defined by Philips®.
