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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.

Detailed 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 DTE or DCE interface port that supports the
V.28 (RS-232), V.11 (RS-449/V.36, EIA530, EIA530-A,
and X.21), and V.35 protocols. The MAX3170 transceiv-
er 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 net-
work or by a discrete termination network.
The MAX3170 features a 1mA no-cable mode, true fail-
safe operation, and thermal shutdown circuitry. Thermal
shutdown protects the drivers against excessive power
dissipation. When activated, the thermal shutdown cir-
cuitry places the driver outputs into a high-impedance
state.
