Functional Features

• Bidirectional data transmission between two buses
• Tri-state outputs for bus isolation
• High-speed operation with minimal power consumption
• ESD (Electrostatic Discharge) protection on all inputs and outputs
• Schmitt-trigger inputs for noise immunity

Advantages

• Fast data transmission with low propagation delay
• Wide supply voltage range allows for compatibility with various systems
• Tri-state outputs enable bus isolation and reduce power consumption
• ESD protection ensures reliability in harsh environments
• Schmitt-trigger inputs provide robustness against noise

Disadvantages

• Limited number of bits (16) may not be suitable for applications requiring larger data buses
• TSSOP package may require careful handling during assembly to prevent damage

Working Principles

The SN74ABT16244ADLG4 is a 16-bit bus transceiver that enables bidirectional data transfer between two buses. It operates by controlling the direction of data flow using the OE (Output Enable) pins. When the OE pin is active, the device allows data to pass from one bus to the other. When the OE pin is inactive, the outputs are tri-stated, isolating the buses.

Detailed Application Field Plans

The SN74ABT16244ADLG4 is commonly used in various applications, including:

1. Data communication systems
2. Memory interfaces
3. Industrial automation
4. Automotive electronics
5. Networking equipment
