The MAX13080E-MAX13089E is a high-performance RS-485/RS-422 transceiver series produced by Texas Instruments. This series of products has one driver and one receiver, supports half-duplex and full-duplex communication, and the receiver output high level will not cause error even if all terminal devices disable the driver. The series supports 250kbps, 500kbps and 16Mbps transmission rates and has hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.
The MAX13080E‑MAX13089E family are +5 V, +15 kV ESD‑protected RS‑485/RS‑422 transceivers with fail‑safe receivers, hot‑swap capability, and selectable full‑/half‑duplex operation. Devices offer reduced‑slew‑rate drivers for up to 250 kbps, 500 kbps, or up to 16 Mbps depending on the part, and support up to 256 transceivers on a single bus.
Typical applications include utility meters, lighting systems, industrial control, telecom, security systems, instrumentation, and Profibus. The parts are offered in 8‑pin and 14‑pin PDIP and SO packages and operate over commercial, extended, and automotive temperature ranges.
