具有三态输出时钟驱动器 CLOCK DRIVER WITH 3-STATE OUTPUTS
The CDC339 is a high-performance, low-skew clock driver. It is specifically designed for applications requiring synchronized output signals at both the primary clock frequency and one-half the primary 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 input is low and the clear input is high, the Y outputs follow CLK and the Q outputs toggle on low-to-high transitions of CLK. Taking low asynchronously resets the Q outputs to the low level. When is high, the outputs are in the high-impedance state.
The CDC339 is characterized for operation from -40°C to 85°C.
