  • Wide operating voltage range of 2V to 6V
  • High-current outputs drive up to 15 LSTTL loads
  • 3-state outputs drive bus lines or buffer memory address registers
  • Low power consumption: ICC, 80µA (maximum)
  • Typical tpd = 11ns
  • ±6mA output drive at 5V
  • Low input current of 1µA (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.

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.
