Overview
The SN64BCT25244DW is a 25-Ω 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 transceivers. It features a state-of-the-art BiCMOS design that significantly reduces the quiescent current (ICCZ) and includes high-impedance state during power up and power down. The device is capable of sinking 188-mA IOL, facilitating the switching of 25-Ω transmission lines on the incident wave.
