MAX13174E
+5V Multiprotocol, Pin-Selectable
Cable Terminator
_______________________________________________________________________________________

Detailed Description
The MAX13174E contains six pin-selectable multiproto-
col cable termination networks (Figure 3). Each network
is capable of terminating V.11 (RS-422, RS-530,
RS-530A, RS-449, V.36, and X.21) with a 100
Ω differen-
tial 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 that have on-chip termination. The termina-
tion 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 designed to form a com-
plete +5V cable- or pin-selectable multiprotocol DCE/DTE
interface port when used with the MAX13170E and
MAX13172E transceivers. The MAX13174E terminator
can use the VEE power generated by the MAX13170E
charge pump, simplifying system design. The
MAX13174E/MAX13170E/MAX13172E are functionally
compatible with the MXL1344A/MXL1543/MXL1544/
MAX3175.
Termination Modes
The termination networks in the MAX13174E can be set
to one of three modes: V.11, V.35, or high impedance.
As shown in Figure 4, in V.11 mode, switch S1 is closed
and switch S2 is open, presenting 104
Ω across termi-
nals A and B. In V.35 mode, switches S1 and S2 are
both closed, presenting a T-network with 104
Ω differen-
tial impedance and 153
Ω common-mode impedance.
In high-impedance mode, switches S1 and S2 are both
open, presenting a high impedance across terminals A
and B suitable for V.28 and V.10 modes.
