maxim 13174e is a multi-protocol cable termination network that supports v.11 and v.35 termination and can be selected by serial interface cable wiring or pin control, replacing the discrete resistor termination networks and expensive relays required for multi-protocol termination, saving space and cost.
The MAX13174E is a +5 V multiprotocol cable terminator that provides six pin‑selectable termination networks. Each network can terminate V.11 (RS‑422, RS‑530, RS‑530A, RS‑449, V.36, X‑21) with a 100 Ω differential load, V.35 with a T‑network load, or V.28/RS‑232 and V.10/RS‑423 with an open‑circuit load. The termination protocol is selected via four mode‑select pins (MO, M1, M2, DCE/DTE) or by cable wiring.
The device is supplied in a 24‑pin SSOP package, operates from 0 °C to +70 °C, and is RoHS‑compliant. Electrical characteristics such as supply voltage ranges, differential‑mode impedance, and absolute maximum ratings are provided, along with pin descriptions, typical application circuits, and mode‑selection tables.
| Supply Voltage (VCC) Range | 4.5 V to 5.5 V |
|---|---|
| Supply Voltage (VEE) Range | -7.1 V to -4 V |
| Operating Temperature Range | 0 °C to +70 °C |
| Package Type | 24‑Pin SSOP |

The device provides six independent pin‑selectable termination networks.
Pins MO, M1, M2, and DCE/DTE are the mode‑select inputs that determine the termination protocol.
