SN74LS244DW

The SN74LS244DW from Texas Instruments is an octal buffer and line driver designed for improved performance and density in bus-oriented applications. This device features 8 non-inverting buffer channels, each with 3-state outputs, allowing them to drive bus lines or buffer memory address registers effectively.

Operating within a supply voltage range of 4.75V to 5.25V, the SN74LS244DW offers high-speed performance with a maximum propagation delay of 15 ns at 5V. It is suitable for applications requiring compatibility with 3.3-V or 2.5-V logic inputs, as its inputs are tolerant down to 2V. The device also includes features like input clamp diodes to reduce DC loading and hysteresis at inputs for improved noise margins.

Packaged in a 20-SOIC (Surface Mount) format, the SN74LS244DW is designed for standard through-hole or surface-mount assembly. Its operating temperature range is from 0°C to 70°C (TA), making it suitable for a variety of commercial and industrial environments. The 3-state outputs are controlled by output-enable inputs, providing flexibility in system design.

This buffer IC is ideal for use in memory address drivers, clock drivers, and bus transceivers where efficient signal buffering and control are essential. Its robust design and specific features contribute to reliable operation in digital systems.
