Product Details

The MAX13171E along with the MAX13173E/ MAX13175E, form a complete pin-selectable data terminal equipment (DTE) or data communication equipment (DCE) interface port that support the V.28 (RS-232), V.10/V.11 (RS-449/V.36, RS-530, RS-530A, X.21), and V.35 protocols. The MAX13171E transceivers carry the high-speed clock and data signals, while the MAX13173E transceivers carry the control signals. The MAX13171E can be terminated by the MAX13175E pin-selectable resistor termination network. The MAX13175E contains six pin-selectable, multiprotocol cable termination networks.

The MAX13171E/MAX13173E have an internal charge pump and low-dropout transmitter output stages that allow V.10-, V.11-, V.28-, and V.35-compliant operation from a single supply. The MAX13171E/MAX13173E feature a no-cable mode that reduces supply current and disables all transmitter and receiver outputs (high impedance). Short-circuit current limiting and thermal shutdown circuitry protects the receiver and transmitter outputs against excessive power dissipation. The MAX13171E/MAX13173E have extended ESD protection for all the transmitter outputs and receivers inputs.

The MAX13171E/MAX13173E/MAX13175E operate over the +3.135V to +5.5V supply range and are available in 5mm x 7mm, 38-pin TQFN packages. These devices operate over the -40°C to +85°C extended temperature range.
