Description

The PI6C180 is a high-speed low-noise 1-18 noninverting buffer designed for SDRAM clock buffer applications.
PI6C180 can operate up to 100 MHz, whereas PI6C180A is rated at 125 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.
