(OE). On the positive transition of the clock, the Q outputs will be set to the logic state that were setup at the D inputs (HC574) or their complements (HC564). While the OE input is low, the eight outputs will be in a normal logic state (high or low logic level), and while high level, the outputs will be in a high impedPIN CONNECTION (top view)
ance state. The output control does not affect the internal operation of flip-flops. That is, the old data can be retained or the new data can be entered even while the outputs are off. The application engineer has a choice of combination of invertin... |
