Disadvantages: - Limited supply voltage range (2 V to 6 V) - Relatively small input and output capacitance

Working Principles

The SN74AC533DBRE4 is an octal transparent latch that stores data and provides 3-state outputs. The latch enable (LE) signal controls the storage of data, while the output enable (OE) signal enables or disables the outputs. When LE is high, the latch stores the data present at the inputs. When OE is low, the outputs are in the high-impedance state, allowing other devices to drive the shared bus. The latch operates at high speed and consumes low power.
