Working Principles

The SN74ACT533DBR operates as an octal transparent latch with 3-state outputs. It stores digital data using D-type flip-flops and allows for non-inverting output control. The latch enable (LE) input controls the data storage operation, while the output enable (OE) input enables or disables the outputs. When LE is high, the data inputs are transferred to the outputs. When OE is low, the outputs are enabled and reflect the stored data. The IC operates at high speed and can handle a wide range of supply voltages.
