The MM78C29 is a dual differential line driver that also performs the dual four-input NAND or dual four-input AND function. The absence of a clamp diode to V_CC in the input protection circuitry of the MM78C29 allows a CMOS user to interface systems operating at different voltage levels. Thus, a CMOS digital signal source can operate at a V_CC voltage greater than the V_CC voltage of the MM78C30 line driver. The differential output of the MM78C29 eliminates ground-loop errors.
