SN74LV244A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 SN74LV244A octal buffers and line drivers are designed for 2-V to 5.5-V VCC operation.

The SN74LV244A devices are designed specifically to improve both performance and density of the 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs.
