Product details

Eight-channel LVDS driver for high-speed serial links

The Texas Instruments SN75LVDS389DBT is an eight-channel LVDS line driver designed for point-to-point and multidrop data transmission over controlled-impedance media.

The driver inputs are LVTTL/LVCMOS-compatible, so a 3.3 V logic source drives them without level translation. 5 V logic inputs are not within the guaranteed input threshold range — if the upstream controller runs at 5 V, a level shifter or resistive divider is needed to avoid overdrive.

Housed in a 38-pin TSSOP (4.40 mm body width), the SN75LVDS389DBT shares the same footprint as the wider SN75LVDS389 family.

Temperature grade limits the deployment envelope

It belongs in office equipment, consumer displays, and indoor telecom gear — not in engine bays, outdoor enclosures, or factory-floor cabinets where ambient can push past 70°C.

Frequently asked questions

Is SN75LVDS389DBT compatible with 3.3 V?

Yes. The LVTTL/LVCMOS inputs also accept 3.3 V logic levels directly.

Can SN75LVDS389DBT drive a display?

It can drive the serial LVDS link to a flat-panel display — the eight channels are enough for a single-link 18-bit or 24-bit interface. The driver itself is the transmit side; you still need a compatible LVDS receiver at the panel end.

Is SN75LVDS389DBT compatible with 5 V logic?

Not directly. The inputs are LVTTL/LVCMOS rated for 3.3 V operation. Driving them with 5 V logic exceeds the recommended input voltage range and risks damage — use a level translator or a resistive divider.
