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
• Low-noise non-inverting 1-18 buffer
• Supports up to four SDRAM DIMMs
• Low skew (< 250ps) between any two output clocks
• I2C Serial Configuration interface
• Multiple VDD, VSS pins for noise reduction
• 3.3V power supply voltage
• Separate Hi-Z pin for testing
• Packaging: (Pb-free and Green)
