四路高速差分线路驱动器 16-CFP -55 to 125
DESCRIPON
The DS26LS31MQML is a quad differential line driver designed for digital data transmission over balanced lines. The DS26LS31MQML 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 DS26LS31MQML features TRI-STATE outputs and logically ANDed complementary outputs. The inputs are all LS compatible and are all one unit load.
The DS26LS31 features a power up/down protection circuit which keeps the output in a high impedance state TRI-STATE during power up or down preventing erroneous glitches on the transmission lines.
