描述 The DS26LS31 is a quad differential line driver designed for digital data transmission over balanced lines. The DS26LS31 meets all the requirements of EIA Standard RS-422 and Federal Standard 1020. It is designed to provide unipolar differential drive to twisted-pair or parallel-wire transmission lines.The circuit provides an enable and disable function common to all four drivers. The DS26LS31 features TRI-STATE outputs and logically ANDed complementary outputs. The inputs are all LS compatible and are all one unit load.特性O(shè)utput Skew—2.0 ns Typical Input to output delay—10 ns Typical Operation from Single 5V Supply Outputs Won't Load Line when VCC = 0V Four Line Drivers in One Package for Maximum Package Density Output Short-Circuit Protection Complementary Outputs Meets the Requirements of EIA Standard RS-422Pin Compatible with AM26LS31 Available in Military and Commercial Temperature Range All trademarks are the property of their respective owners.
