Multiprotocol, Pin-Selectable
Data Interface Chipset
/MAX3175E
General Description
Features
♦ Supports V.28 (RS-232), V.10 (RS-423), V.11
The MAX13171E along with the MAX13173E/
MAX13175E, form a complete pin-selectable data termi-
nal equipment (DTE) or data communication equipment
(DCE) interface port that support the V.28 (RS-232),
V.10/V.11 (RS-449/V.36, RS-530, RS-530A, X.21), and
V.35 protocols. The MAX13171E transceivers carry the
high-speed clock and data signals, while the MAX13173E
transceivers carry the control signals. The MAX13171E
can be terminated by the MAX13175E pin-selectable
resistor termination network. The MAX13175E contains six
pin-selectable, multiprotocol cable termination networks.
(RS-449/V.36, RS-530, RS-530A, X.21) and V.35
Protocols
♦ Pin-Selectable Cable Termination Using the
MAX13175E
♦ Pin-Selectable DCE/DTE Configurations
♦ 20/40Mbps (max) Data Rate in RS-449, RS-530,
RS-530A, X.21, and V.35
♦ True Fail-Safe Receivers while Maintaining V.11
and V.35 Compatibility
The MAX13171E/MAX13173E have an internal charge
pump and low-dropout transmitter output stages that
allow V.10-, V.11-, V.28-, and V.35-compliant operation
from a single supply. The MAX13171E/MAX13173E fea-
ture a no-cable mode that reduces supply current and
disables all transmitter and receiver outputs (high imped-
ance). Short-circuit current limiting and thermal shutdown
circuitry protects the receiver and transmitter outputs
against excessive power dissipation. The MAX13171E/
MAX13173E have extended ESD protection for all the
transmitter outputs and receivers inputs.
