Functional Features

  • Bidirectional data transfer between two independent buses
  • 3-state outputs allow multiple devices to share the same bus
  • High-speed operation with minimal propagation delay
  • Low-voltage operation for reduced power consumption
  • ESD protection for enhanced reliability

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer - Low-voltage operation reduces power consumption - 3-state outputs facilitate bus sharing among multiple devices - ESD protection enhances reliability in harsh environments

Disadvantages: - Limited number of bits (16) may not be suitable for applications requiring larger data buses - TSSOP package may require careful handling during assembly

Working Principles

The SN74ALVCH162721DLR is designed to enable bidirectional data transfer between two independent buses. It utilizes a combination of input/output buffers, control logic, and 3-state output drivers to achieve this functionality. The direction of data flow is controlled by the DIR pin, while the OEAB and OEB pins control the output enable for each bus. When the output is disabled, the outputs are in a high-impedance state, allowing other devices to drive the bus.

Detailed Application Field Plans

The SN74ALVCH162721DLR is commonly used in various digital systems where bidirectional data transfer between buses is required. Some potential application fields include:

  1. Microprocessors and Microcontrollers
