The SN74ALS667NT is a high-quality octal bus transceiver from Texas Instruments designed for asynchronous communication between data buses. The device allows data transmission from the A bus to the B bus and vice versa, depending on the logic level at the direction control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

Key Features

• Bi-Directional Interface: The SN74ALS667NT features eight bi-directional lines that allow for versatile two-way communication.
• High-Speed Data Transfer: With ALS technology, this transceiver is capable of transferring data at high speeds, suitable for demanding applications.
• Output Enable (OE): The inclusion of the OE input allows the transceiver outputs to be isolated from the bus lines, providing added control over data flow.
• Direction Control (DIR): The direction of data flow is controlled by the DIR input, making the device flexible for various data transmission requirements.
• Low-Power Schottky Circuitry: The use of Low-Power Schottky (LPS) technology ensures minimal power consumption while maintaining high-speed operation.

Applications

The SN74ALS667NT is ideal for a variety of applications where reliable data transfer between two buses is required. This includes, but is not limited to, data communication in microprocessor or microcontroller systems, data multiplexing, and memory switching operations. Its robust design and high-speed capabilities make it a suitable choice for industrial, commercial, and telecommunications applications.

Quality and Reliability

As with all Texas Instruments components, the SN74ALS667NT is manufactured to the highest quality standards, ensuring reliability and performance in even the most demanding conditions. The device is available in a 20-pin DIP package, making it easy to integrate into a wide range of electronic circuits.
