The MS2576T is a low power four-channel differential line driver chip for balanced or unbalanced digital data transmission. It can meet the requirements of ANSITIA\/EIA-422- and ITU (formerly CCITT) Recommendation V.11.

The three-state output provides a high current to drive balanced lines such as twisted pair or parallel two-wire transmission lines, and is in a high impedance state in case of power failure. Each of the four drivers has an enable function, which provides two optional inputs: a high active enable and a low Active Enable (G,GN) input. The MS2576T is packaged in TSSOP16.
