Working Principles

The 74ACT533SC operates based on the principles of digital logic. When the latch enable (LE) input is activated, the data inputs (D0-D7) are latched and stored internally. The output enable (OE) input controls whether the stored data is presented at the outputs (Q0-Q7). When the OE input is active, the outputs reflect the stored data. Conversely, when the OE input is inactive, the outputs enter a high impedance state, allowing other components to drive the bus.
