ON Semiconductor MC74HCT244A Octal 3-State Non-Inverting Buffer/Line Driver

The MC74HCT244A from ON Semiconductor is a high-performance, octal non-inverting buffer/line driver designed to interface with 5V systems. With its advanced silicon-gate CMOS technology, it provides the ability to drive lines or buffer memory address registers while maintaining the low power consumption of CMOS with the speed and drive capabilities of LSTTL. The MC74HCT244A is compatible with industry-standard HCT logic products.

This device features eight non-inverting buffers with 3-state outputs, making it an excellent choice for driving bus lines or buffering memory address registers. The 3-state outputs allow for connection to a bus-oriented system without the need for external pull-up resistors. When the output-enable (OE) input is high, the outputs are in a high-impedance state, which helps in sharing a common bus line.

Each buffer has a separate output-enable input, which can be used to place the output in either a normal logic level or the high-impedance state. Additionally, the MC74HCT244A has a broad operating voltage range from 4.5V to 5.5V, making it versatile for interfacing with different logic levels and ensuring reliable operation in a variety of circuits.

The device's inputs are compatible with TTL levels, which allows for direct interfacing with TTL logic without the need for additional level shifters. This feature simplifies the design process and reduces component count, contributing to a more efficient and cost-effective design.

ON Semiconductor's MC74HCT244A comes in a variety of packages, including the 20-lead DIP, 20-lead SOIC, and 20-lead TSSOP, providing flexibility for different space requirements and PCB layouts. With its industry-standard footprint, this device is easy to integrate into existing designs or use in new projects.

Whether you're designing data buses, memory address drivers, or need a reliable buffer for your digital systems, the MC74HCT244A offers a robust solution with the quality and reliability expected from ON Semiconductor.
