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.
