Functional Features

The 74HCT373DB,112 is a transparent latch with eight data inputs (D0-D7) and eight corresponding outputs (Q0-Q7). It operates on the rising edge of the latch enable (LE) signal. When the output enable (OE) signal is low, the latch is transparent, allowing the data inputs to pass through to the outputs. When the LE signal transitions from low to high, the latch stores the data inputs and holds them at the outputs until the next transition of the LE signal.

Advantages and Disadvantages

Advantages

• High-speed operation allows for efficient data transfer.
• Low power consumption makes it suitable for battery-powered devices.
• Compatibility with both CMOS and TTL logic levels enables easy integration into various digital systems.
• Wide operating voltage range provides flexibility in different applications.
• Schmitt-trigger action on all inputs ensures reliable operation in noisy environments.

Disadvantages

• Limited number of data inputs and outputs restricts its use in applications requiring more extensive data storage and transfer capabilities.
• The SSOP package may not be suitable for certain space-constrained designs.

Working Principles

The 74HCT373DB,112 functions as a latch by storing and transferring data based on the control signals (LE and OE). When the LE signal rises, the latch captures the data inputs and holds them at the outputs until the next rising edge of the LE signal. The OE signal controls the output enable/disable state, allowing or preventing the data from propagating to the outputs.

Detailed Application Field Plans

The 74HCT373DB,112 finds applications in various digital systems, including but not limited to: - Microcontrollers - Data storage devices - Address decoders - Memory modules - Communication interfaces
