Disadvantages: - Limited voltage range (4.5V to 5.5V) - Propagation delay may affect timing-sensitive applications

Working Principles

The SN74BCT373DWG4 is an octal transparent latch that stores data and controls its output based on clock and control signals. When the latch enable (LE) signal is high, the data inputs (D0-D7) are latched to the outputs (Q0-Q7) on the rising edge of the clock pulse (CP). The output enable (OE) signal determines whether the outputs are in a high-impedance state or actively driving the bus.
