FAIRCHILD MM88C29

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.)

Typical Applications
Digital Data Transmission
Note A: Exact value depends on line length.
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.
