An internal register remembers the last key pressed even after the key is released. Device also available in Tape and Reel.

The internal debounce circuit needs only a single external capacitor and can be defeated by omitting the capacitor. Pin Assignment for DIP.

The Data Available output returns to a low level when the entered key is released, even if another key is depressed. A Data Available output goes to a high datqsheet. The keyboard scan can be implemented by either an external clock or external capacitor.

An internal register remembers the last key pressed even. No diodes in the switch array are needed to eliminate ghost switches.
