General Description
The MAX3170 is a three-driver/three-receiver multipro-
tocol transceiver that operates from a +3.3V single sup-
ply. The MAX3170, along with the MAX3171/MAX3173
and MAX3172/MAX3174, form a complete software-
selectable data terminal equipment (DTE) or data com-
munications 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 sig-
nals, while the MAX3171 or MAX3173 carries the con-
trol signals. The MAX3170 can be terminated by the
MAX3172 or MAX3174 software-selectable resistor ter-
mination 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 shut-
down circuitry protect the drivers against excessive
power dissipation.
