RS-485/RS-422 transceiver for industrial bus networks
It delivers a 20 Mbps data rate, making it suitable for high-speed industrial automation, building management, and telecom equipment where signal integrity over twisted-pair cabling is critical.
20 Mbps signaling — bus timing and cable length trade-offs
At 20 Mbps, the SN65HVD3088EDGKRG4 supports the faster end of RS-485 signaling, typically used for shorter bus segments (under 100 meters) or point-to-point links where throughput matters more than reach. For longer cable runs or lower data rates, the same part works at slower speeds without modification — the 20 Mbps rating is the maximum, not a fixed operating point.
This means Texas Instruments has announced end-of-life for this specific order code, and the final production window is active. Once the last-time-buy period closes, the part will no longer be manufactured. For existing designs, this triggers a sourcing decision: secure lifetime buy inventory now, or qualify a replacement. The base product number 65HVD3088 shares the same die and functional behavior across package variants, but the EDGKRG4 suffix (8-VSSOP, Tape & Reel) is the specific variant being phased out.
Package and footprint — 8-VSSOP for space-constrained boards
The surface-mount footprint matches the standard 8-MSOP/TSSOP land pattern, so a layout designed for one accepts the other. The single driver and single receiver pair (1/1) covers point-to-point or multi-drop RS-485 networks with one transceiver per node.
