CDC337 - 1-To-8 (4 Same Frequency, 4 Divide-By-2) Clock Driver With Clear

The CDC337 is a high-performance, low-skew clock driver. It is specifically designed for applications requiring synchronized output signals at both the clock frequency and one-half the clock frequency. The four Y outputs switch in phase and at the same frequency as the clock (CLK) input. The four Q outputs switch at one-half the frequency of CLK.

When the output-enable (OE\) input is low and the clear (CLR\) input is high, the Y outputs follow CLK and the Q outputs toggle on low-to-high transitions at CLK. Taking CLR\ low asynchronously resets the Q outputs to the low level. When OE\ is high, the outputs are in the high-impedance state.

The CDC337 is characterized for operation from -40°C to 85°C.
