SN74HC240N

74HC 系列反相器和缓冲器，Texas InstrumentsTexas Instruments 的 74HC 系列 CMOS Logic IC 的一系列反相器和缓冲器。 74HC 系列使用硅门 CMOS 技术，实现与 LSTTL 系列类似的工作速度，但标准 CMOS 集成电路功耗降低。### 74HC 系列

The is an Octal Buffer and Line Driver designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, bus-oriented receivers and transmitters. The HC240 device is 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.
