The keyboard scan can be implemented. Pin Assignment for DIP. Fairchild Semiconductor Electronic Components Datasheet. Order Number Package Number. The Data Available will return high to indicate acceptance of the new key after a normal debounce period; this two-key roll-over is provided between any two switches. The keyboard scan can be implemented by either an external clock or external capacitor. A Data Available output goes to a high level. The Data Available output returns to a low level when the entered key is released, even if another key is depressed.
