Maxim MAX13170E Datasheet

General Description
The MAX13170E is a three-driver/three-receiver multipro­tocol transceiver that operates from a +5V single supply. The MAX13170E, along with the MAX13172E and the MAX13174E, form a complete software-selectable data terminal equipment (DTE) or data communication equip­ment (DCE) interface port that supports the V.28 (RS-232), V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A, X.21), and V.35 protocols. The MAX13170E transceivers carry the high-speed clock and data signals, while the MAX13172E carry the control signals. The MAX13170E can be termi­nated by the MAX13174E software-selectable resistor termination network or by discrete termination networks.
The MAX13170E has an internal charge pump and a proprietary low-dropout transmitter output stage that allows V.11-, V.28-, and V.35-compliant operation from a +5V single supply. The MAX13170E features a no­cable mode that reduces supply current to 0.5µA, and disables all (high-impedance) transmitter and receiver outputs. Short-circuit current limiting and thermal shut­down circuitry protect the receiver and transmitter out­puts against excessive power dissipation. The MAX13170E has extended ESD protection for all the transmitter outputs and receivers inputs.
The MAX13170E is available in a 5.3mm x 10.2mm, 28-pin SSOP package and operates over the 0°C to +70°C commercial temperature range.
