ON Semiconductor 74LVTH244SJ: High-Speed Octal Buffer/Line Driver with 3-State Outputs

The ON Semiconductor 74LVTH244SJ is a high-performance, octal buffer/line driver designed to facilitate the interfacing between low-voltage, high-speed logic circuits and other circuitry while maintaining signal integrity. This integrated circuit is part of the 74LVTH family, which is characterized by its low-voltage operation and high tolerance to input voltages, making it suitable for mixed-voltage applications.

The 74LVTH244SJ is equipped with two sets of eight buffers, each with 3-state outputs that can be independently controlled. This feature allows for greater flexibility in bidirectional data flow and bus-oriented systems, ensuring that multiple devices can share common data lines without interference. The 3-state outputs also enable the device to be placed in a high-impedance state, effectively disconnecting it from the bus, which is essential for preventing bus contention issues.

With its ability to operate at a nominal voltage of 3.3V, the 74LVTH244SJ is optimized for low-voltage applications that require fast data transfer rates and low power dissipation. The device is characterized for operation from -40°C to +85°C, making it reliable in a wide range of environmental conditions.

The 74LVTH244SJ features a flow-through pinout, which simplifies the PCB layout by allowing the input and output connections to be placed on opposite sides of the package. This design minimizes the length of the signal paths and reduces the effects of signal skew, ensuring faster and more reliable operation.

ON Semiconductor has packaged the 74LVTH244SJ in a slim, 20-lead Small Outline package (SOIC), which is ideal for space-constrained applications. The device also includes built-in bus-hold circuitry, which maintains the last active logic level on the inputs when they are left floating, reducing the need for external pull-up or pull-down resistors.

In summary, the ON Semiconductor 74LVTH244SJ is a versatile and robust octal buffer/line driver that is perfect for high-speed digital systems that require low-voltage operation and the ability to drive heavy loads with minimal power consumption.
