Octal Buffers/Drivers With 3-State Outputs

 

Description

These SNx4ACT244 octal buffers and drivers are designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

The SNx4ACT244 devices are organized as two 4-bit buffers and drivers with separate output-enable (OE) inputs. When OE is low, the device passes non-inverted data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.

Features

  • 4.5-V to 5.5-V VCC Operation
  • Inputs Accept Voltages to 5.5 V
  • Max tpd of 9.5 ns at 5 V
  • Inputs are TTL Compatible
  • 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.
