Product Summary

The NTE74S257 is a quad 2−line to 1−line data selector/multiplexer in a 16−lead plastic DIP-type package designed to multiplex signals from four−bit data sources to four−output data lines in bus−organized systems. The 3−state outputs will not load the data lines when the output control pin (G) is at a high-logic level.

  • Three−state outputs interface directly with system bus
  • Provide bus interface from multiple sources in high−performance systems
  • Supply voltage VCC: 7V
  • Input voltage VIN: 5.5V
  • Off−state output voltage: 5.5V
  • Operating temperature range TA: 0°C to +70°C
  • Storage temperature range Tstg: −65°C to +150°C
