Octal Buffers And Line Drivers With 3-State Outputs

 

Description

The SNx4HC244 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 SNx4HC244 devices are organized as two 4-bit buffers and 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.

Features

  • 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: ICC, 80-µA (Maximum)
  • Typical tpd = 11 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 µA (Maximum)
  • On Products Compliant to MIL-PRF-38535,
    All Parameters Are Tested Unless Otherwise
    Noted. On All Other Products, Production
    Processing Does Not Necessarily Include
    Testing of All Parameters.
