MAX3172 Datasheet | Maxim Integrated

19-1801; Rev 1; 1/01 +3.3V Multiprotocol Software-Selectable Cable Terminators and Transceivers General Description The MAX3172/MAX3174 contain five software-selectable multiprotocol cable termination networks. Each network is capable of terminating V.11 (RS-422, RS530, 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 plete +3.3V...
