ON Semiconductor MC74VHCT244ADWRG Octal Buffer/Line Driver

The MC74VHCT244ADWRG is a high-performance, octal buffer/line driver designed by ON Semiconductor, a leading provider of semiconductor-based solutions. This device is part of the VHCT family and is created to interface between 3.3V and 5V systems. With the capability to operate as a non-inverting buffer or line driver, it is well-suited for driving bus lines or buffer memory address registers, providing a high degree of flexibility and utility in a variety of applications.

The device features advanced silicon-gate CMOS technology, which ensures minimal power consumption while maintaining high-speed operation. The MC74VHCT244ADWRG can operate with a supply voltage range of 4.5V to 5.5V, making it compatible with TTL levels, and it is guaranteed to be over-voltage tolerant to 5.5V, providing additional reliability and robustness in mixed-voltage environments.

Each buffer/line driver has a separate input-enable (E) pin, which when held high, disables the respective buffer and forces its outputs to a high-impedance state. This feature allows for the isolation of the buses, making it easier to manage multiple bus connections and reducing the potential for bus contention. The device is also equipped with 3-state outputs, which are essential for bus-oriented applications.

ON Semiconductor's MC74VHCT244ADWRG is offered in a 20-lead SOIC package, which is widely accepted in the industry and known for its small footprint and ease of PCB layout. This package is also suitable for automated assembly processes, supporting high-volume production requirements.

In summary, the MC74VHCT244ADWRG from ON Semiconductor is a versatile and efficient solution for systems requiring high-speed, low-power octal buffer/line drivers. With its advanced CMOS technology, 3-state outputs, and over-voltage tolerance, it stands as a reliable choice for designers looking to bridge 3.3V and 5V logic systems in a variety of digital applications.
