MAX3171/MAX3173
+3.3V Multiprotocol 3Tx/3Rx
Software-Selectable Control Transceivers

_______________________________________________________________________________________
Detailed Description
The MAX3171/MAX3173 are three-driver/three-receiver
multiprotocol transceivers that operate from a single
+3.3V supply. The MAX3171/MAX3173, along with the
MAX3170 and MAX3172/MAX3174, form a complete
software-selectable DTE or DCE interface port that sup-
ports the V.28 (RS-232), V.10/V.11 (RS-449, V.36, EIA-
530, EIA-530-A, X.21, RS-423), and V.35 protocols. The
MAX3171/MAX3173 carry the control signals, while the
MAX3170 transceiver carries the high-speed clock and
data signals. The MAX3172/MAX3174 provide termina-
tion for the clock and data signals and have an extra
transceiver for applications requiring four transceivers
for control handshaking.
The MAX3171/MAX3173 feature a 2mA no-cable mode,
true fail-safe operation, and thermal shutdown circuitry.
Thermal shutdown protects the drivers against exces-
sive power dissipation. When activated, the thermal
shutdown circuitry places the driver outputs into a high-
impedance state.
Mode Selection
The state of mode select pins M0, M1, and M2 determines
which serial interface protocol is selected (Table 1). The
state of the DCE/DTE input determines whether the trans-
ceivers will be configured as a DTE serial port or a DCE
serial port. When the DCE/DTE input is logic HIGH, dri-
ver T3 is activated and receiver R1 is disabled. When
the DCE/DTE input is logic LOW, driver T3 is disabled
and receiver R1 is activated. M0, M1, M2, and
DCE/DTE are internally pulled up to VCC to ensure logic
HIGH if left unconnected.
The MAX3171/MAX3173’s mode can be selected
through software control of the M0, M1, M2, and
DCE/DTE inputs. Alternatively, the mode can be select-
ed by shorting the appropriate combination of mode
control inputs to GND (the inputs left floating will be
internally pulled up to VCC). If the M0, M1, and M2
mode inputs are all unconnected, the MAX3171/
MAX3173 will enter no-cable mode.
