说明：

这些八进制缓冲区和线司机是特别设计来改善两者的性能和密度的三状态内存地址司机,时钟驱动、总线式接收器和发射器。“HC244设备被组织成两个4比特缓冲/司机与单独的允许输出(OE)\输入。当OE \低,这个装置通过noninverted数据从一个输入输出Y。当OE \高,输出在高阻抗状态

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 ’HC244 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE)\ inputs. When OE\ is low, the device passes noninverted data from the A inputs to the Y outputs. When OE\ is high, the outputs are in the high-impedance state

特性：

  • Wide Operating Voltage Range of 2 V to 6 V
  • High-Current Outputs Drive Up To 15 LSTTL Loads
  • 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
  • Low Power Consumption, 80-µA Max ICC
  • Typical tpd = 11 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA Max
