Description
The MC74HC244ADTR2G is a high-speed CMOS octal buffer/line driver with 3-state outputs. Designed for a wide range of voltage levels, it operates within a range of 2V to 6V, making it suitable for various applications in digital circuits where buffering data and driving bus lines are required. Each of the eight channels can be individually controlled, and the device features two enable inputs (1OE and 2OE) for group control of the outputs. The 3-state outputs allow for direct connection to bus lines, enabling the outputs to be in a high-impedance state when not driving the load, preventing conflicts with other devices. Its low power consumption and ability to drive significant output loads make it ideal for interfacing with TTL, NMOS, and CMOS devices. Packaged in a TSSOP-20 configuration, the MC74HC244ADTR2G is suited for space-constrained applications and is commonly used in computers, networking equipment, and other digital systems.
