Product Description

The 74HCT244APWR is engineered to provide high-drive outputs with minimal propagation delay, making it an ideal choice for driving bus lines or buffer memory address registers in a wide range of applications. With its octal configuration, it can handle eight separate input/output lines, allowing for efficient data management and signal distribution.

The device features two separate control inputs for each set of four buffers, granting precise control over output states. When in the high-impedance state, the outputs neither load nor drive the bus lines significantly, thus reducing power consumption and preventing bus contention.

Manufactured with advanced silicon-gate CMOS technology, the 74HCT244APWR ensures reduced power consumption and increased noise immunity. The TSSOP-20 package provides a compact, surface-mount solution suitable for densely packed PCBs, while the wide operating temperature range makes it suitable for industrial and automotive applications.

Whether you are designing a microprocessor/microcontroller system interface, extending signal lines, or requiring a temporary data storage solution, the 74HCT244APWR offers a reliable and efficient performance that meets the rigorous standards of today's electronic systems.
