The recommended power-up sequence is to apply VCC first, followed by VEE, and then the input signals. This ensures proper device operation and prevents potential latch-up conditions.
The OE pin should be tied low (active) when the device is driving the bus, and high (inactive) when the device is in a high-impedance state. This ensures proper bus control and prevents data corruption.
The maximum frequency of operation for the CDC857-2DGGR is 100 MHz. However, this frequency may vary depending on the specific application, capacitive loading, and other system factors.
Yes, the CDC857-2DGGR can be used as a level translator between 3.3V and 5V logic levels. However, ensure that the input and output voltage levels are within the recommended operating ranges specified in the datasheet.
The proper termination resistors for the CDC857-2DGGR depend on the specific application, bus loading, and signal frequency. A general rule of thumb is to use a series termination resistor (Rs) of 22-33 ohms and a parallel termination resistor (Rt) of 47-68 ohms. However, it's recommended to consult the datasheet and perform simulations to determine the optimal termination values for your specific design.
