Frequently Asked Questions
What is the difference between transparent and latching modes?
When LE is HIGH, the latches are in transparent mode (D follows Q); when LE is LOW, they latch and store the input data.
How can this device be used in bus-oriented applications?
It features a common 3-state output enable (OE) input that controls all eight latches simultaneously for clean bus driving.
What are the minimum timing requirements?
The required minimum set-up time is 13 ns, and the minimum hold time is 9 ns (specific to the family used).
How do I calculate the power dissipation?
Dynamic power is calculated using the formula: P = C × V × f + ∑ (C × V × f), where C, V, and f are capacitance, voltage, and frequency.
