PI6C180B Datasheet PDF - Pericom Semiconductor Corporation

Description
The PI6C180B, a high-speed low-noise 1-18 noninverting buffer designed for 140 MHz SDRAM clock buffer applications.
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.

FEATUREs
• High-speed, to 140 MHz
