STMicroelectronics 74LVC244ATTR Octal Buffer/Line Driver

The 74LVC244ATTR from STMicroelectronics is a high-performance, octal buffer and line driver designed to ensure robust signal integrity while driving heavy loads. This integrated circuit is part of the LVC family, which operates at a lower voltage and with better performance than traditional logic gate ICs. It is particularly suitable for interfacing with 3.3V and 5V systems, making it a versatile choice for a wide range of applications.

Featuring eight non-inverting buffer/line drivers with 3-state outputs, the 74LVC244ATTR is ideal for driving bus lines or buffer memory address registers. Each buffer has a separate output enable pin, which allows for greater control and flexibility in managing the flow of data. The device supports an operating voltage range of 1.65V to 5.5V, which facilitates its use in mixed-voltage environments and ensures compatibility with both legacy and modern systems.

With its advanced 5V tolerant inputs, the 74LVC244ATTR can receive high logic-level signals while operating at a lower voltage without risk of damage. This feature is particularly beneficial when interfacing with 5V logic levels in mixed-voltage systems. The device also boasts a high noise immunity characteristic of the LVC family, ensuring stable operation even in electrically noisy environments.

The 74LVC244ATTR is available in a TSSOP-20 package, which is optimized for reduced space and weight in printed circuit board designs. Its compact form factor, along with the option for tape and reel packaging, makes it an excellent choice for automated assembly processes, particularly in mass production settings.

Key features of the 74LVC244ATTR include its high-speed performance, with propagation delays significantly lower than those of standard logic ICs, and its ability to drive up to 24mA of output current. It also offers a low power consumption, which is critical for battery-operated and power-sensitive applications. Whether used in computing, telecommunications, or consumer electronics, the STMicroelectronics 74LVC244ATTR is an effective solution for reliable signal buffering and driving.
