WebDec 31, 2024 · The time borrowing technique, is also called cycle stealing, occurs at a latch. In a latch, one edge of the clock makes the latch transparent, that is, it opens the latch so that output of the latch is the same as the data input;this clock edge is called the opening edge. The second edge of the clock closes the latch, that is, any change on the ...
In digital electronics, the fan-out is the number of gate inputs driven by the output of another single logic gate. In most designs, logic gates are connected to form more complex circuits. While no logic gate input can be fed by more than one output at a time without causing contention, it is common for one output to … See more Maximum limits on fan-out are usually stated for a given logic family or device in the manufacturer's datasheets.
