SN54HC240中文资料具有三态输出的军用 8 通道、2V 至 6V 反相器数据手册TI规格书

描述 Description

These octal buffers and line 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 ’HC240 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE)\\ inputs. When OE\\ is low, the device passes inverted data from the A inputs to the Y outputs. When OE\\ is high, the outputs are in the high-impedance state.
