Overview
The SN64BCT757DWR is an octal buffer and line driver produced by 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 features a BiCMOS design, which significantly reduces the ICCZ (quiescent current) and provides high ESD protection. The device operates over a wide temperature range from –40°C to 85°C and is available in various package options, including SOIC and DIP packages.
