The DS7830 is a dual differential line driver that also performs the dual four-input NAND or dual four-input AND function. TTL (Transistor-Transistor-Logic) multiple emitter inputs allow this line driver to interface with standard TTL systems. The differential outputs are balanced and are designed to drive long lengths of coaxial cable, strip line, or twisted pair transmission lines with characteristic impedances of 50 to 500. The differential feature of the output eliminates troublesome ground-loop errors normally associated with single-wire transmissions.
