The MAX14780E is a half-duplex serial communication transceiver from MAXIM with ±30kV ESD protection, 1/8 unit load receiver input impedance, and error-free data transmission at a data rate of 500kbps.
The MAX14780E is a +5 V, +30 kV ESD‑protected RS‑485/RS‑422 transceiver with fail‑safe receiver, hot‑swap capability, and reduced slew‑rate drivers for error‑free data transmission up to 500 kbps. It supports half‑duplex communication, draws low supply current, and allows up to 256 transceivers on a single bus.
The datasheet details absolute maximum ratings, DC electrical characteristics, driver and receiver switching timings, and typical application circuits. Package options include 8‑pin SO and PDIP, and the document lists ordering information, thermal‑shutdown thresholds, and revision history.
