description

The CDC391 contains a clock-driver circuit that distributes one input signal to six outputs with minimum skew

for clock distribution. Through the use of the polarity-control (T/C) inputs, various combinations of true and

complementary outputs can be obtained. The output-enable (OE) input is provided to disable the outputs to a

high-impedance state.

The CDC391 is characterized for operation from − 40

°C to 85°C.
