The MAX3172/MAX3174 contain five software-selectable 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 differential 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 networks 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 selectable 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.
