Revised June 2001 MM88C29 • MM88C30 Quad Single-Ended Line Driver • Dual Differential Line Driver General Description 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. Features ■ Wide supply voltage range: 3V to 15V ■ High noise immunity: 0.45 VCC (typ.) ■ Low output ON resistance: 20Ω (typ.)

Note B: Optional to control response time. Note C: VCC= 4.5V to 5.5V for the DS7820, VCC=4.5V to 15V for the DS78C20. VCC is 3V to 15V. Typical Data Rate vs Transmission Line Length Note: The transmission line used was #22 gauge unshielded twisted pair (40k termination). Note: The curves generated assume that both drivers are driving equal lines, and that the maximum power is 500 mW/package. 5 www.fairchildsemi.com MM88C29 • MM88C30 Typical Performance Characteristics MM88C29 Typical Propagation Delay vs. Load Capacitance MM88C30 Typical Propagation Delay vs. Load Capacitance MM88C29 Typical Propagation Delay vs. Load Capacitance Typical Sink Current vs. Output Voltage Typical Source Current vs. Output Voltage MM88C30 Typical Propagation Delay vs. Load Capacitance www.fairchildsemi.com 6 MM88C29 • MM88C30 Physical Dimensions inches (millimeters) unless otherwise noted 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Package Number M14A 7 www.fairchildsemi.com MM88C29 • MM88C30 Quad Single-Ended Line Driver • Dual Differential Line Driver Physical Dimensions inches (millimeters) unless otherwise noted (Continued) 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Package Number N14A Fairchild does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and Fairchild reserves the right at any time without notice to change said circuitry and specifications.
