Product Description

The SN74ABT861DWR is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as two 8-bit transceivers or one 16-bit transceiver, as it 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.

With its robust construction, the SN74ABT861DWR ensures signal integrity with a high drive capability and is suitable for driving heavily loaded buses. It is packaged in a 24-pin SOIC, which makes it compact and ideal for space-constrained applications.

The device is characterized for operation from -40°C to 85°C, ensuring reliability in a wide range of environments. The SN74ABT861DWR also features typical edge rates and propagation delays that are fully specified to provide consistent performance.

Whether you're designing high-speed data acquisition systems, telecommunications interfaces, or need a reliable bus transceiver for your digital circuit, the SN74ABT861DWR from Texas Instruments is a choice that promises to deliver both performance and durability.
