8305I - Block Diagram
描述
The 8305I is a low skew, 1-to-4, Differential/LVCMOS-to- LVCMOS/LVTTL Fanout Buffer. The 8305I has selectable clock inputs that accept either differential or single ended input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Outputs are forced LOW when the clock is disabled. A separate output enable pin controls whether the outputs are in the active or high impedance state. Guaranteed output and part-to-part skew characteristics make the 8305I ideal for those applications demanding well defined performance and repeatability.
