MAX13170E
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.

Note 1: Package thermal resistances were obtained using the method described in JESD51-7, using a 4-layer board. For detailed
information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
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.
ELECTRICAL CHARACTERISTICS
(VCC = 4.5V to 5.5V, C3 = C4 = C5 = 4.7µF, C1 = C2 = 1µF, TA = TMIN to TMAX. Typical values are at VCC = 5V, and TA = +25°C.)
