Labview latch
Webdata latch. The undefined state is removed by forcing R and S to always be complementary. This improvement is made at the expense of the "no change" state. Despite this, the D FF is still extremely useful. Notice that the NAND gate in figure 3-4 with both inputs tied together acts like an inverter, without having to use another chip.
