- Either DSA or DSB can be used as an active high enable for data entry through the other input.
- Otherwise, Both inputs must be connected together or an unused input must be tied high.
Note: Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
