Twelve Channel CMOS Differential Line Driver
General DescriptionThe DS89C387isa high speed twelve channel CMOS dif-
ferential driver that meets the requirementsof TIA/EIA-
422-B. The DS89C387 featuresa low ICC specificationof
1.5mA maximum, which makesit idealfor battery powered
and power conscious applications. The device replaces
three DS34C87s and offersaPC board space savingsupto
30%. The twelve channel driveris availableina SSOP
package. The deviceis idealfor wide parallel bus applica-
tions.
Each TRI-STATE® enable (EN) allows the driver outputsto activeorina HI-impedanceoff state. Each enableis
commonto only two driversfor flexibility and control. The
drivers maybe disabledto turnoff load current andto save
power when datais not being transmitted.
The driver’s input (DI)is compatible with both TTL and
CMOS signal levels.
Features Low power ICC: 1.5 mA maximum Meets TIA/EIA-422-B (RS-422) GuaranteedAC parameters: Maximum driver skew −3ns Maximum transition time −10ns Availablein SSOP packaging: Requires 30% less PCB space than3 DS34C87TMs
