Functional Features

The 74LVC373APW,118 is an octal D-type transparent latch with 3-state outputs. It features a latch enable (LE) input and an output enable (OE) input. When the LE input is high, the latch is transparent, allowing the data inputs to appear at the outputs. The OE input controls the 3-state outputs, enabling or disabling them.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Wide supply voltage range - 3-state outputs for bus-oriented applications

Disadvantages: - Limited number of latch outputs - Not suitable for applications requiring more than 8 latch outputs

Working Principles

The 74LVC373APW,118 operates by latching the data inputs when the latch enable (LE) input is high. The latched data appears at the outputs when the output enable (OE) input is also high. When the OE input is low, the outputs are in a high-impedance state, effectively disconnecting them from the rest of the circuit.

Detailed Application Field Plans

The 74LVC373APW,118 is commonly used in various digital logic applications, including but not limited to: - Data storage and transfer in microprocessors - Address decoding in memory systems - Bus interface in computer systems - Control signal buffering in communication systems
