+3.3V Multiprotocol Software-Selectable

Cable Terminators and Transceivers

General Description

Features

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 100Ω 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.
