Working Principles

The SN74LVTH373DWR is a transparent latch that stores and transfers data. It operates on a low-voltage supply, making it compatible with modern integrated circuits. The latch has eight data inputs (D0-D7) and corresponding outputs (Q0-Q6). The latch enable (LE) signal controls the storage of data, while the output enable (OE) signal enables or disables the outputs.

When the latch enable signal is high, the inputs are transparently transferred to the outputs. This means that any changes in the input data will be immediately reflected at the outputs. When the latch enable signal is low, the outputs hold their previous state, regardless of any changes in the input data.

The output enable signal determines whether the outputs are active or in a high-impedance state. When the output enable signal is high, the outputs are active and can drive external circuitry. When the output enable signal is low, the outputs enter a high-impedance state, allowing other devices to control the bus.
