Functional Features

The SN74ABT16245ADGVR is a high-speed, bi-directional 16-bit buffer and transceiver. It allows bidirectional transfer of data between two buses operating at different voltage levels. The device features non-inverting outputs and provides a high output drive strength of ±24mA. It operates within a wide voltage range of 2V to 5.5V, making it compatible with various logic families.

Advantages and Disadvantages

Advantages: - High-speed data transfer - Bi-directional functionality - Non-inverting outputs - Wide operating voltage range - High output drive strength

Disadvantages: - Limited number of bits (16-bit) - Requires careful consideration of voltage compatibility between buses

Working Principles

The SN74ABT16245ADGVR works by receiving data from one bus and transmitting it to the other bus bidirectionally. The direction of data flow is controlled by the DIR pin. When DIR is set to a specific logic level, the device either transmits data from Bus A to Bus B or from Bus B to Bus A. The OE pins are used to enable or disable the outputs, allowing for tri-state operation when necessary.

Detailed Application Field Plans

The SN74ABT16245ADGVR is commonly used in applications where data needs to be
