Timing relationship of OE# to the dual-port

Last Updated: June 11, 2011

What is the timing relationship between OE# and CE# in synchronous Dual Ports? - How is the output enable signal connected to the clocks?


OE# is an asynchronous signal. That means there is no direct relationship between this signal and the clocks or any other synchronous signal. Basically, OE# controls the state of the data bus. It is either driving data or in a high impedence state. The data bus reacts to the OE# signal switching from high-to-low or low-to-high without any regard to the state of the rest of the device.
