Product Description

The SN74AC244DWG4 is a high-speed octal buffer and line driver designed to be used in bus-oriented systems. The device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the input side to the output side. Conversely, when OE is high, the outputs are in a high-impedance state, which means that they neither drive nor load the bus significantly.

The 3-state outputs are necessary to allow multiple devices to share a bus line without interference. This feature makes the SN74AC244DWG4 ideal for use in systems that require a high degree of control over data flow, such as computers, communication systems, and advanced industrial control systems.

The SN74AC244DWG4 operates over a broad voltage range of 2V to 6V and offers symmetrical output impedance. It features -24mA IOL for better output drive capability. This makes it suitable for interfacing with high-speed logic systems. The device is also characterized for operation from -40°C to 85°C, ensuring reliable performance in a wide range of environments.

The device comes in a SOIC-20 package, which is a small outline package that is easy to handle and suitable for space-constrained applications. The SN74AC244DWG4 from Texas Instruments is a versatile component that provides a reliable solution for digital signal buffering and driving applications.
