The MM88C30 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 VCC in the input protection circuitry of the MM88C30 allows a CMOS user to interface systems operating at different voltage levels. Thus, a CMOS digital signal source can operate at a VCC voltage greater than the VCC voltage of the MM88C30 line driver. The differential output of the MM88C30 eliminates ground-loop errors.
The MM88C29 is a non-inverting single-wire transmission line driver. Since the output ON resistance is a low 20Ω typ., the device can be used to drive lamps, relays, solenoids, and clock lines, besides driving data lines.
■ Wide supply voltage range: 3V to 15V
■ High noise immunity: 0.45 VCC (typ.)
■ Low output ON resistance: 20Ω (typ.)
