Maxim MAX3030E-MAX3033E RS-422 Transmitter Datasheet
The MAX3030E‑MAX3033E family are quad RS‑422 transmitters designed for digital data transmission over balanced lines, meeting TIA/EIA‑422‑B and ITU‑T V.11 standards. They are offered in 2 Mbps and 20 Mbps guaranteed baud rates and feature low‑static current consumption for battery‑powered applications.
Key features include +15 kV ESD protection on driver outputs, hot‑swap functionality, low‑power design (<330 µW at 3.3 V), and availability in 16‑pin TSSOP and narrow SO packages. The devices operate from –40 °C to +85 °C and provide propagation delays as low as 16 ns with part‑to‑part skew under 5 ns.
