Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
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.
