Functional Features

  • Octal transparent D-type latches with 3-state outputs
  • Latches are transparent when the output enable (OE) is high
  • When OE is low, the latches store the data present at the inputs
  • 3-state outputs allow multiple devices to be connected to a common bus without contention

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer - 3-state outputs facilitate bus-oriented applications - Wide operating voltage range allows compatibility with various systems - Low power consumption reduces energy usage

Disadvantages: - Limited number of latches per package (eight in this case) - May require additional components for specific applications

Working Principles

The SN74AC373DBR operates by using transparent D-type latches to store and transfer data. When the output enable (OE) is high, the latches become transparent, allowing the data on the inputs to pass through to the outputs. When OE is low, the latches hold the data that was present at the inputs when OE transitioned from high to low.

Detailed Application Field Plans

The SN74AC373DBR can be used in various applications, including: - Data storage and transfer in microcontrollers and microprocessors - Address decoding in memory systems - Bus interfacing in communication systems - Register storage in digital systems

Detailed and Complete Alternative Models

Some alternative models that provide similar functionality to the SN74AC373DBR are: - SN74HC373: Octal D-Type Transparent Latches with 3-State Outputs - CD74ACT373: Octal Transparent Latch with 3-State Outputs - MC74AC373: Octal Transparent Latch with 3-State Outputs

These alternative models offer comparable features and can be used as substitutes depending on specific requirements.
