Overview
The SN74AHC16244DGGR is a 16-bit buffer and line driver produced by Texas Instruments. It is part of the SNx4AHC16244 family, designed to enhance the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer, providing true outputs and symmetrical active-low output-enable (OE) inputs. The SN74AHC16244 is characterized for operation from –40°C to 85°C, making it suitable for a wide range of applications where low-drive CMOS devices are required.
