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 100
dif-
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.
