5V Multiprotocol, Pin-Selectable Cable Terminator

The MAX13174E contains six pin-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 termination protocol can be selected by the serial interface cable wiring or by pin control. The MAX13174E replaces discrete resistor termination networks and expensive relays required for multiprotocol termination, saving space and cost.

The MAX13174E terminator is ideal to form a complete +5V cable- or pin-selectable multiprotocol DCE/DTE interface port when used with the MAX13170E and MAX13172E transceiver ICs. The MAX13174E terminator can use the VEE power generated by the MAX13170E charge pump, simplifying system design. The MAX13174E/MAX13170E/MAX13172E are pin-for-pin compatible with the MXL1344A/MXL1543/MXL1544/MAX3175.

The MAX13174E is available in a 24-pin SSOP package and is specified for the 0°C to +70°C commercial temperature range.
