Product details

155 Mbps full-duplex LVDS — what it buys you

The Texas Instruments SN75LVDS179D is an LVDS transceiver delivering a single differential driver and a single differential receiver in a full-duplex configuration. Rated for 155 Mbps data rate, it handles point-to-point serial links where simultaneous bidirectional transmission over a single pair is not required — the driver and receiver operate independently on separate pairs. Full-duplex means the receiver stays active while the driver is enabled, which simplifies handshake-free data flow but demands careful termination on both differential pairs to maintain signal integrity at the rated speed.

Sourcing reality — obsolete part, no direct successor

Pin-compatible alternatives exist within the broader LVDS transceiver family (e.g., parts sharing the SN75LV base product number), but without a manufacturer-specified successor, each alternate should be validated against the original's full-duplex pinout, 155 Mbps timing, and 3.3V supply tolerance.

Temperature grade and package — indoor, surface-mount only

The 155 Mbps edge rate demands controlled-impedance traces on the differential pairs.

Frequently asked questions

Is SN75LVDS179D obsolete?

Yes, the SN75LVDS179D is listed as Obsolete. Texas Instruments no longer manufactures this part, and no official replacement order code has been provided in the record. Sourcing is limited to independent distribution channels — new-old-stock, surplus, or verified reels.

What is the data rate of SN75LVDS179D?

The SN75LVDS179D is rated for 155 Mbps data rate. This full-duplex LVDS transceiver supports simultaneous driver and receiver operation at that speed, making it suitable for point-to-point serial links in telecom and industrial control.

Is SN75LVDS179D compatible with 3.3V?

Yes. The LVDS output levels are compatible with 3.3V logic families on the receiver side, and the differential inputs meet the LVDS common-mode range across that supply.
