Functional Features

The MC74LCX373DTR2 is an octal transparent latch with 3-state outputs. It allows data to be latched and stored when the latch enable (LE) signal is high. The latch remains transparent as long as the LE signal is high, allowing the input data to pass through to the outputs. When the LE signal goes low, the latch becomes opaque, holding the last latched data.

The 3-state outputs of the MC74LCX373DTR2 provide flexibility in connecting multiple devices together. When the output enable (OE) signal is high, the outputs are in a high-impedance state, allowing other devices to drive the bus lines.

Advantages and Disadvantages

Advantages: - Low-voltage operation - High-speed performance - Wide operating voltage range - 3-state outputs for bus sharing applications

Disadvantages: - Limited number of bits (8 bits) - Not suitable for high-voltage applications

Working Principles

The MC74LCX373DTR2 operates based on the principles of CMOS technology. It utilizes a combination of NMOS and PMOS transistors to achieve low-voltage operation and high-speed performance. The latch enable (LE) signal controls the transparency of the latch, while the output enable (OE) signal determines the state of the outputs.

Detailed Application Field Plans

The MC74LCX373DTR2 is commonly used in various digital logic applications, including but not limited to: - Data storage and transfer systems - Address decoding circuits - Bus interface units - Memory modules - Microprocessor-based systems
