ON Semiconductor MC74HCT244AFELG Octal Buffer/Line Driver

The ON Semiconductor MC74HCT244AFELG is a high-performance integrated circuit designed to function as an octal buffer and line driver with 3-state outputs. It is a crucial component for systems that require the ability to drive heavy loads or need isolation between input and output lines to protect the integrity of data signals. This device is particularly suitable for driving bus lines or buffer memory address registers due to its high drive current and robust output stage.

Constructed with advanced silicon-gate CMOS technology, the MC74HCT244AFELG offers the best of both worlds: the low power consumption of CMOS circuitry and the ability to interface with LSTTL logic levels. This makes it compatible with a variety of digital systems, ensuring seamless integration with both CMOS and LSTTL components. Its compatibility is further enhanced by its wide operating voltage range of 4.5V to 5.5V, which allows it to be used in diverse operational environments.

The device features eight non-inverting buffers with 3-state outputs, which can be placed in a high-impedance state effectively isolating the outputs from the bus lines. This is controlled by two output enable (OE) inputs, one for each set of four buffers. The MC74HCT244AFELG's 3-state outputs enable multiple units to be connected to the same bus line, which is essential for bus-oriented systems.

ON Semiconductor's MC74HCT244AFELG is offered in a 20-lead SOIC package, ensuring a compact footprint ideal for space-constrained applications. Its operating temperature range spans from -55°C to +125°C, providing reliable performance under extreme conditions. Furthermore, the device has a low power consumption with a typical ICC of 4µA, which is beneficial for power-sensitive designs.

Whether it's for interfacing with high-speed microprocessors, driving bus lines, or buffering memory address registers, the MC74HCT244AFELG is an exemplary choice for designers who require a dependable and versatile octal buffer/line driver. Its robust design, compatibility with various logic levels, and power efficiency make it a valuable component in a wide array of digital applications.
