Texas Instruments SN74LVC258A Quad 2-to-1 Line Data Selector/Mux

Texas Instruments SN74LVC258A Quad 2-to-1 Line Data Selector/Multiplexer contains four 2-to-1 digital multiplexers with inverted outputs. The output enable (OE) input enables all outputs when low and forces them into the high-impedance state when high. The select (A/B) input of the Texas Instruments SN74LVC258A chooses the data source for all channels, with the low state indicating the A data source and the high state indicating the B data source.

Features

  • Operating range from 1.1V to 3.6V
  • Over-voltage tolerant inputs support up to 5.5V independent of VCC
  • Supports partial power down with back drive protection (Ioff)
  • Maximum propagation delay of 6.4ns at 3V
  • High push-pull output drive strength
    • ±24mA at 3.3V
    • ±8mA at 2.3V
    • ±4mA at 1.65V
  • Latch-up performance exceeds 100mAper JESD78

Applications

  • Data selection
  • Multiplexing
