Overview
The SN74ABT16244ADGGRG4 is a 16-bit buffer/driver with 3-state outputs, part of the Widebus™ Family from Texas Instruments. This device is designed to enhance the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The SN74ABT16244A series features state-of-the-art EPIC-IIB™ BiCMOS design, which significantly reduces power dissipation.
