MAX13174E Datasheet, PDF (1/13 Pages) Maxim Integrated Products – +5V Multiprotocol, Pin-Selectable Cable Terminator

19-4742; Rev 0; 7/09
+5V Multiprotocol, Pin-Selectable
Cable Terminator
General Description
The MAX13174E contains six pin-selectable, multiproto-
col cable termination networks. Each network is capa-
ble 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 trans-
ceivers having on-chip termination. The termination pro-
tocol can be selected by the serial interface cable
wiring or by pin control. The MAX13174E replaces dis-
crete 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 termina-
tor can use the V_EE 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 tem-
perature range.
