MAX3172CAI+-MAX3172EAI+T
+3.3V Multiprotocol Software-Selectable Cable Terminators and Transceivers
General Description
The MAX3172/MAX3174 contain five software-selec-
table multiprotocol cable termination networks. Each
network is capable of terminating V.11 (RS-422, RS-
530, RS-530A, RS-449, V.36, and X.21) with a 100Ωdif-
ferential load, V.35 with a T-network load, or V.28
(RS-232) and V.10 (RS-423) with an open circuit load
for use with transceivers having on-chip termination.
The devices replace discrete resistor termination net-
works and expensive relays required for multiprotocol
termination. The MAX3172/MAX3174, along with the
MAX3170 and MAX3171/MAX3173, form a complete
+3.3V software-selectable DTE or DCE interface port
supporting V.11/RS-422, RS-530, RS-530A, V.36/RS-
449, V.35, V.28/RS-232, V.10/RS-423, and X.21 serial
interfaces.
In addition to the five multiprotocol cable termination
networks, the MAX3172/MAX3174 contain a 1Tx/1Rx
multiprotocol transceiver designed to use V+ and V-
generated by the MAX3171/MAX3173 charge pump.
The MAX3172/MAX3174 transceiver is software selec-
table between V.10 and V.28 modes of operation. The
MAX3172 features 10µs deglitching on the V.10/V.28
receiver input to facilitate unterminated operation, while
the MAX3174 is used in applications that do not require
deglitching on the serial handshake signals. These
devices are available in a 28-pin SSOP package.

Note 2:
The charge pump on the MAX3171/MAX3173 can supply V+ and V- to the MAX3172/MAX3174. The V+ and V- input levels
vary with the mode of chipset operation as follows:
V.35/V.28 modes: +5.55V ≤V+ ≤+6.50V, -6.50V ≤V- ≤-5.45V
Typical operation: V+ = +5.90V, V- = -5.80V

The MAX3171/MAX3173 are guaranteed to provide these V+/V- supply levels.

MAX3172/MAX3174
+3.3V Multiprotocol Software-Selectable
Cable Terminators and Transceivers
Detailed Description

The MAX3172/MAX3174 contain five software-selectable
multiprotocol cable termination networks. Each network is
capable of terminating V.11 transceivers (RS-422, RS-
530, RS-530A, RS-449, V.36, and X.21) with a 100Ωdif-
ferential load, V.35 transceivers with a T-network load, or
V.28 (RS-232) and V.10 transceivers (RS-423) with an
open circuit load. The MAX3172/MAX3174, along with the
MAX3170 and MAX3171/MAX3173, form a complete
+3.3V software-selectable DTE or DCE interface port sup-
porting V.11/RS-422, RS-530, RS-530A, V.36/RS-449,
V.35, V.28/RS-232, V.10/RS-423, and X.21 serial inter-
faces.
The MAX3172/MAX3174 also contain a multiprotocol
transceiver that is software-selectable between V.10 and
V.28 operation modes. This transceiver is intended as the
handshake signal I/O in a DCE/DTE port application, and
is designed to use V+ and V- levels generated by the
MAX3171/MAX3173 charge pump. The MAX3172 fea-
tures 10µs deglitching on the V.10/V.28 receiver input to
allow unterminated operation. The MAX3174 is used in
applications that do not require deglitching on the serial
handshake signals.
No-Cable Mode

The MAX3172/MAX3174 enter no-cable mode when the
mode-select inputs are all HIGH (M0 = M1 = M2 = 1). In
this mode, the driver, receiver, and bias circuitry are dis-
abled, and the supply current drops to less than 200µA.
In no-cable mode, all five termination networks are
placed in the V.11 mode of operation (shorting pins R_A
and R_B with a 100Ωresistor). The receiver output enters
a high-impedance state in no-cable mode, allowing this
output line to be shared with other receivers (the receiver
output has an internal pullup resistor to pull the output
HIGH if not driven). Also, in no-cable mode, the transmit-
ter output enters a high-impedance state so that this out-
put can be shared with other devices.
Cable Termination

The MAX3172/MAX3174 software-selectable resistor net-
works are intended for use with the MAX3170 clock/data
transceiver chip. The termination network is used for the
V.11, V.35, and V.28 transmitters. The MAX3172/
MAX3174 provide the advantage of not having to build
expensive termination networks from resistors and relays,
manually changing termination modules, or building ter-
mination networks into custom cables.
Each termination network can be in one of three modes:
V.35, V.11, or high impedance (high-Z) as shown in
Figure 5 (see Table 2). For example, in V.35 mode, all five

networks are configured to provide 100Ωdifferential
impedance and 150Ωcommon-mode impedance to ter-
minate the MAX3170 V.35 transmitter outputs and receiv-
er inputs.
Termination Mode Selection

The mode-select pins M0, M1, M2, and DCE/DTEcontrol
the state of the five termination networks (Table 1). The
mode-select table of the MAX3172/MAX3174 is compati-
ble with the MAX3170 mode-select table so that the M0,
M1, M2, and DCE/DTEpins can be connected to the cor-
responding pins on the MAX3170. For example, M2 = 1,
M1 = 0, M0 = 0 corresponds to V.35 mode for both the
MAX3172/MAX3174 and the MAX3170 clock/data trans-
ceiver chip.
R4/T4 Mode Selection

The MAX3172/MAX3174 include a transceiver for use in
applications requiring an extra serial handshake signal
(for example, local loopback). The transceiver can be
