Demonstration of a tri-state buffer (also called a three-state switch).
Input: D (data), E (enable)
Output: W (write)
When E = 1, W is equal to D
When E = 0, W = Z (high impedance, "floating", "disconnected")
D E W
0	0	Z
1	0	Z
0	1	0
1	1	1

Set D high or low (press 1). Set E high or low (press 2). Observe the output W.
