Product details

LVDS transceiver for 155 Mbps serial links

The part is packaged in a 16-SOIC surface-mount package, suitable for point-to-point or multidrop LVDS interconnects in telecom, industrial, and data-acquisition backplanes.

What 155 Mbps means for your link budget

The 155 Mbps data rate is the maximum signaling speed per channel. For LVDS, this translates to a typical cable length of several meters over twisted-pair or differential PCB traces, limited by signal attenuation and skew. The full-duplex architecture allows simultaneous transmit and receive on separate differential pairs, which halves the cable count compared to half-duplex schemes. The 2/2 driver/receiver count supports two independent full-duplex links or one link with redundant paths.

Frequently asked questions

What is a direct replacement for SN75LVDS051DRG4?

No official direct replacement is listed by Texas Instruments. The base product number SN75LVDS051 may have active variants in different packages (e.g., SN75LVDS051D in SOIC-16), but the DRG4 suffix indicates a specific reel and environmental data code variant. Pin-compatibility should be verified against the datasheet for any candidate. The part is best sourced through surplus channels for legacy designs.

Is SN75LVDS051DRG4 still available for purchase?

Yes, through independent distribution. The part is obsolete from the manufacturer but can be procured on the open market. Each order is quoted individually with confirmed availability and pricing.
