74LS244 Description

Short technical summary and product information.

The SN74LS244 from Texas Instruments is an octal buffer and line driver designed for improved performance and density in bus-oriented applications. This device features eight non-inverting buffers with 3-state outputs, controlled by an output-enable input. It is suitable for driving bus lines or buffering memory address registers.

Key electrical characteristics include a supply voltage range of 4.75-V to 5.25-V, a maximum supply current of 50 mA, and a maximum propagation delay of 15 ns at 5V. The inputs are tolerant down to 2V and compatible with 3.3-V or 2.5-V logic, while PNP inputs reduce DC loading. The device offers a 400-mV noise margin.

Available in various package types including SOP, SOIC, SSOP, and PDIP, the SN74LS244 is designed for commercial applications with an operating temperature range of 0°C to 70°C. Its 3-state outputs allow for efficient bus driving and memory address buffering.
