• Non-Inverting: The input and output signals have the same logic level.
• High-Speed Operation: Provides fast data transfer with a propagation delay of only 3.8ns.
• Output Enable Control: Allows the user to enable or disable the outputs using the OE (Output Enable) pin.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer. - Non-inverting feature simplifies the design of digital systems. - Output enable control provides flexibility in managing the outputs.

Disadvantages: - Limited to 16-bit bus width, may not be suitable for applications requiring larger data buses. - Requires a stable power supply within the specified voltage range for reliable operation.

Working Principles

The SN74ABT16244ADLR acts as a bidirectional buffer/driver for data transmission between two buses. It uses non-inverting logic, meaning that the input and output signals have the same logic level. The IC operates at high speed, allowing fast data transfer with minimal delay.

The device has separate input/output pins for Bus A and Bus B, enabling bidirectional communication. The output enable (OE) pin controls the activation of the outputs. When OE is low, the outputs are enabled, and data can flow between the buses. Conversely, when OE is high, the outputs are disabled, isolating the buses from each other.

Detailed Application Field Plans

The SN74ABT16244ADLR is commonly used in various digital systems where bidirectional data transfer is required. Some application fields include:

1. Microprocessors: Facilitates communication between the microprocessor and external devices.
2. Memory Systems: Enables data transfer between memory modules and the system bus.
3. Communication Interfaces: Used in UARTs, SPI, or I2C interfaces for data exchange.
4. Data Acquisition Systems: Transfers data between sensors and processing units.
5. Industrial Automation: Connects different modules in control systems for data sharing.
