Product Overview: 74ACTQ244SJX from ON Semiconductor

The 74ACTQ244SJX is a high-performance, octal buffer/line driver designed by ON Semiconductor to address the requirements of high-speed data transmission systems. This integrated circuit is part of the ACTQ family, which is recognized for its quiet series technology, ensuring reduced noise levels in digital systems. The 74ACTQ244SJX is specifically crafted to improve both the signal integrity and the power consumption profiles of electronic assemblies.

With its eight non-inverting buffers and line drivers, the 74ACTQ244SJX offers a robust solution for driving bus lines or buffering memory address registers. Each buffer has a 3-state control, allowing for efficient connection to bus lines. This feature is particularly useful in applications where multiple peripherals are connected to a common bus, as it enables each device to disconnect from the bus when not in use, thereby preventing contention.

The device is built using advanced CMOS technology, which provides high speed yet minimizes power consumption. The 74ACTQ244SJX operates within a voltage range of 4.5V to 5.5V, making it compatible with TTL levels, and it is characterized for operation from -40°C to +85°C, ensuring reliability across a wide range of environmental conditions.

One of the key features of the 74ACTQ244SJX is its bus hold circuitry on each data input. This innovative design eliminates the need for external pull-up or pull-down resistors, simplifying board design and reducing overall component count. Moreover, the device's inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages exceeding VCC.

The 74ACTQ244SJX is packaged in a 20-lead small outline package (SOIC), with a package code of SJX, making it suitable for space-constrained applications. Its package design ensures a compact footprint on printed circuit boards, facilitating high-density mounting and contributing to the miniaturization of electronic systems.

In summary, the 74ACTQ244SJX from ON Semiconductor is an exemplary choice for system designers looking for a reliable, high-performance octal buffer/line driver. With its advanced features and robust design, it is well-suited for a variety of applications, including computing, telecommunications, and industrial control systems.
