SN65HVD3088E Low-Power RS-485 Transceiver

Specifications

Product Overview

The SN65HVD3088E is a Texas Instruments low-power RS-485 transceiver in the Signal_Chain category. It meets or exceeds TIA/EIA-485A for RS-485 data bus networks and uses a half-duplex transceiver configuration. The device operates from a 5 V nominal supply, with a recommended VCC range of 4.5 to 5.5 V over the operating free-air temperature range.

For network design, SN65HVD3088E provides a 20 Mbps maximum signaling rate and presents a 1/8 unit load, allowing up to 256 nodes on a compatible RS-485 bus. Receiver fail-safe behavior covers bus-open, bus-shorted, and bus-idle conditions. Recommended bus terminal voltage is -7 to 12 V, and recommended differential input voltage is -12 to 12 V.

Package choices include SOIC (D, 8), VSSOP (DGK, 8), PDIP (P, 8), and SO (NS, 14). In the 8-pin D, P, and DGK packages, pins include R receive data output, active-low RE, active-high DE, D driver data input, and complementary A and B bus input/output pins. Protection ratings include up to 15 kV bus-pin ESD protection and +/-4000 V electrical fast transient/burst rating on A, B, and GND.

Procurement Notes

When requesting a quote for SN65HVD3088E, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
