MM88C29 * MM88C30 Quad Single-Ended Line Driver * Dual Differential Line Driver
October 1987 Revised January 1999
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 20 typ., the device can be used to drive lamps, relays, solenoids, and clock lines, besides driving data lines.
Features
s Wide supply voltage range: s High noise immunity: 3V to 15V 0.45 VCC (typ.) s Low output ON resistance: 20 (typ.)

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. Except for "Operating Temperature Range" they are not meant to imply that the devices should be operated at these limits. The Electrical Characteristics tables provide conditions for actual device operation. Note 2: AC Parameters are guaranteed by DC correlated testing.

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.
