74ACT16825数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The 'ACT16825 18-bit buffers/drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The 'ACT16825 can be used as two 9-bit buffers or one 18-bit buffer. They provide true data from A to Y.The 3-state control gate is a 2-input NOR gate; therefore, if either output-enable ( or ) input is high, all nine affected outputs are in the high-impedance state.The 74ACT16825 is packaged in TI's shrink small-outline package, which provides twice the I/O pin count and functionality of standard small-outline packages in the same printed-circuit-board area.The 54ACT16825 is characterized for operation over the full military temperature range of -55°C to 125°C. The 74ACT16825 is characterized for operation from -40°C to 85°C.
