The CDC391DR is a clock fanout buffer integrated circuit manufactured by Texas Instruments. Housed in a 16-pin SOIC package with a width of 3.90mm, this component is designed to distribute clock signals efficiently. It operates with TTL logic levels and requires a supply voltage ranging from 4.75V to 5.25V, offering a 1:6 fanout configuration at a frequency of up to 100 MHz. The part does not feature phase-locked loop or skew-adjustment capabilities, focusing solely on the amplification and distribution of input clock signals to multiple outputs.
