Product Summary

The SN74HCT125DR bus buffer gate features independent line drivers with 3-state outputs. Each output is disasbled when the associated output-enable (OE) input is high. The SN74HCT125DR is characterized for operation over the full military temperature range of –55℃ to 125℃. The SN74HCT125DR is characterized for operation from –40℃ to 85℃.
