Description
The PI6C185-02B, a high-speed low-noise 1-7 non-inverting
buffer, is designed for SDRAM clock buffer applications. It 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 seven output drivers.
Note:
Purchase of I2C components from Pericom conveys a license to
use them in an I2C system as defined by Philips.
