MAX3170：+3.3V, Multiprotocol, 3 Tx/3 Rx, Software-Selectable Clock/Data Transceiver

Industry's First +3.3V Multiprotocol Transceiver Intended for Use with Control Signals

The MAX3170 is a three-driver/three-receiver multiprotocol transceiver that operates from a +3.3V single supply. The MAX3170, along with the MAX3171/MAX3173 and MAX3172/MAX3174, form a complete software-selectable data terminal equipment (DTE) or data communications equipment (DCE) interface port that supports the V.28 (RS-232), V.11 (RS-449/V.36, EIA530, EIA530-A, X.21), and V.35 protocols. The MAX3170 transceiver carries the high-speed clock and data signals, while the MAX3171 or MAX3173 carries the control signals. The MAX3170 can be terminated by the MAX3172 or MAX3174 software-selectable resistor termination network or by a discrete termination network. An internal charge pump and proprietary low-dropout transmitter output stage allow V.11-, V.28-, and V.35-compliant operation from a +3.3V single supply. A no-cable mode is entered when all mode pins (M0, M1, and M2) are pulled high or left unconnected. In no-cable mode, supply current decreases to 1mA and all transmitter and receiver outputs are disabled (high impedance). Short-circuit limiting and thermal shutdown circuitry protect the drivers against excessive power dissipation.
