Functional Features

  • Bidirectional data transfer between two independent buses
  • Non-inverting outputs for both A and B buses
  • Output enable (OEAB and OEBA) for controlling the direction of data flow
  • 3-state outputs for disconnected or high-impedance state when not enabled
  • High-speed operation with low power consumption
  • ESD protection for robustness against electrostatic discharge

Advantages and Disadvantages

Advantages: - High-speed data transfer capability - Low power consumption - Robust ESD protection - Easy integration into digital systems

Disadvantages: - Limited number of channels (16) - Requires careful handling to prevent damage from static electricity

Working Principles

The 74ACT16245DGGR is a bidirectional bus transceiver that enables communication between two independent buses in a digital system. It uses non-inverting outputs for both the A and B buses, allowing data to be transferred bidirectionally. The direction of data flow is controlled by the output enable pins (OEAB and OEBA). When these pins are active, the corresponding bus is enabled, and data can be transferred in that direction. When the output enable pins are inactive, the outputs enter a high-impedance state, effectively disconnecting the transceiver from the buses.

Detailed Application Field Plans

The 74ACT16245DGGR is commonly used in various digital systems where bidirectional data transfer between two independent buses is required. Some application fields include:

  1. Microprocessors and microcontrollers
  2. Data communication systems
  3. Networking equipment
  4. Industrial automation
  5. Automotive electronics
  6. Test and measurement instruments
