The 3-state outputs do not load the data lines when the output-enable (OE) input is at a high logic level. The SN54ALS257A and SN54ALS258A are characterized for operation over the full military temperature range of −55 °C to 125°C. The SN74ALS257A, SN74ALS258A, SN74AS257, and SN74AS258 are characterized for operation from 0 °C to 70°C.
