Frequently Asked Questions
How is the output state maintained when latch enable (LE) goes LOW?
When LE goes LOW, the last data present at A inputs are stored in the latches, and the outputs remain stable.
What determines the status of all 16 outputs if the enable input (E) is HIGH?
If E is HIGH, all 16 mutually exclusive outputs (Q to Q) will be high (HIGH).
Can this device function as a demultiplexer?
Yes, when used as a demultiplexer, E acts as the data input and A to A are the address inputs.
