Description
The PI6C180, a high-speed low-noise 1-18 non-inverting buffer
designed for SDRAM clock buffer applications operates up to
100 MHz.
At power up all SDRAM output are enabled and active. The I2C
Serial control may be used to individually activate/deactivate any
of the 18 output drivers.
The output enable (OE) pin may be pulled low to put all outputs
in a Hi-Z state.
Note:
Purchase of I2C components from Pericom conveys a license to
use them in an I2C system as defined by Philips.
