4 verified alternatives for MAX485ESA
| Alternative | Manufacturer | Relationship | Key differences | Source |
|---|---|---|---|---|
| SN65HVD485E | Texas Instruments | Pin-to-pinDrop-in: same footprint and pinout. | TI's improved replacement for MAX485E in the industry-standard 8-pin transceiver pinout (RO/RE/DE/DI/A/B). Differences: 10 Mbps (vs 2.5 Mbps), 15 kV bus ESD, 64 nodes (1/2 unit load vs 32), -40 to +85 C, 5 V. Note: the VSSOP-8 tube variant is marked obsolete on TI - choose the SOIC-8 (D) variant. | TI 官方数据手册 |
| SN75LBC176A | Texas Instruments | Pin-to-pinDrop-in: same footprint and pinout. | Classic differential bus transceiver in the same 8-pin SOIC/PDIP pinout. Differences: up to 30 Mbps, 32 nodes, 12 kV bus ESD, but only 0-70 C commercial temperature (narrower than MAX485ESA's industrial grade). | TI 官方数据手册 |
| ISL8485EIBZ-T | Renesas | Pin-to-pinDrop-in: same footprint and pinout. | ESD-protected 5 V half-duplex transceiver in SOIC-8 with the same pinout as MAX485. Differences: 10 Mbps, 15 kV bus ESD, 32 nodes (single unit load), 4.5-5.5 V supply (10% tolerance), -40 to +85 C industrial grade. | Renesas 官方数据手册 |
| MAX13486E | Analog Devices | Pin-to-pinDrop-in: same footprint and pinout. | ADI's newer 5 V half-duplex RS-485 transceiver in the industry-standard 8-pin pinout. Differences: 16 Mbps, 15 kV ESD protection, hot-swap capability, true fail-safe receiver, and a higher bus node count than MAX485. | ADI 官方页面 |
Pre-replacement checklist
- Confirm half-duplex operation and the standard 8-pin pinout (RO, RE, DE, DI, GND, A, B, VCC) on your board.
- Check the required data rate: MAX485ESA is 2.5 Mbps; replacements range from 10 to 30 Mbps - all fine at or below their maximum.
- Match the bus node count: 32 (MAX485ESA, SN75LBC176A, ISL8485E), 64 (SN65HVD485E), or more (MAX13486E).
- Verify 5 V supply and industrial temperature if the original design depends on them.
