Product details
Overview
MAX13175EETU+ from Maxim Integrated is a pin-selectable, six-channel multiprotocol cable termination network for V.28 (RS-232), V.10 (RS-423), V.11 (RS-449/V.36/RS-530/RS-530A/X.21), and V.35 data interface systems. It provides programmable differential- and common-mode impedance matching (90–110Ω differential, 135–165Ω common-mode in V.35 mode), operates from +3.135V to +5.5V, supports -40°C to +85°C, and integrates enable/disable timing control (≤300µs disable) for use with MAX13171E/MAX13173E transceivers in telecom CSU/DSU and data router port designs.
For engineers reviewing the MAX13175EETU+ datasheet, MAX13175EETU+ pinout, MAX13175EETU+ application, or MAX13175EETU+ equivalent, this page delivers verified electrical specifications, validated pin functions, real-world protocol-specific termination behavior (V.35/V.11), thermal and ESD performance (±15kV HBM), and direct alternative part guidance - all aligned to Maxim's official 10-page electrical characteristics table and typical operating curves.
Technical Context
The MAX13175EETU+ implements six independent, pin-configurable termination networks-each selectable via M0/M1/M2/DCE/DTE inputs-to match protocol-specific load requirements without external resistors. It supports simultaneous V.35 (90–110Ω diff, 135–165Ω cm) and V.11 (100–110Ω diff) impedance standards across full temperature range, with guaranteed differential-path enable/disable times of 50µs and 300µs respectively.
Its logic-controlled termination paths feature high-impedance leakage <±50µA at ±15V input, integrated ESD protection (±15kV HBM, ±10kV air-gap on R_A/R_B), and supply current of 2.15–5.9mA (ICC) under active operation. The device interfaces directly with MAX13171E/MAX13173E transceiver outputs and shares identical 38-pin TQFN-EP (5mm × 7mm) packaging and thermal profile (θJA = 28°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Differential Impedance (V.35) | 90–110Ω - matches RS-449/V.35 standard 100Ω twisted-pair cabling to minimize reflections at up to 40Mbps. |
| Common-Mode Impedance (V.35) | 135–165Ω - ensures balanced common-mode rejection in X.21/RS-530A applications with shielded cables. |
| Supply Voltage Range | +3.135V to +5.5V - compatible with 3.3V and 5V system rails; no level-shifting required for VL logic interface. |
| Operating Temperature | -40°C to +85°C - qualified for industrial telecom equipment, including outdoor CSU/DSU and carrier-grade routers. |
| ESD Protection (R_A/R_B) | ±15kV HBM, ±10kV IEC 61000-4-2 air-gap - protects against field-induced transients on exposed telecom line terminals. |
| Differential Path Disable Time | ≤300µs - enables fast power-down during cable disconnect or protocol reconfiguration without signal corruption. |
| Logic Input Thresholds | VIH = 0.66×VL, VIL = 0.33×VL - supports 1.62V–5.5V logic reference (VL), enabling direct interfacing with 1.8V/2.5V/3.3V controllers. |
Pinout & Package
MAX13175EETU+ is housed in a 38-pin TQFN-EP package (5mm × 7mm, 0.5mm pitch) with exposed thermal pad. Pin functions are defined by M0/M1/M2/DCE/DTE logic inputs and six bidirectional termination channels (R_A/R_B/R_C per channel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| M0, M1, M2 | Termination Mode Select | 3-bit bus defining impedance configuration per channel (e.g., V.35, V.11, or high-Z); pulled up internally (50–170kΩ to VL). |
| DCE/DTE | Protocol Polarity Control | Selects DCE or DTE termination mapping; determines which pins drive differential pairs in full-duplex V.35/V.11 links. |
| R_A, R_B, R_C (x6) | Termination Network Terminals | Bidirectional analog I/O pins connecting to transceiver outputs (e.g., MAX13171E T_OUT_/R_IN_) and cable shields; support ±15V common-mode range. |
| LATCH | Configuration Latch Enable | Edge-triggered input that freezes M0/M1/M2/DCE/DTE settings; prevents mid-operation mode changes during live data transmission. |
| VCC, VL, VEE | Power Supplies | VCC (+3.135–5.5V) powers analog core; VL (1.62–5.5V) sets logic threshold; VEE (-7.1 to -4V) supplies negative rail for V.28-compatible biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Six independent pin-selectable terminations | Enables single-component support for mixed-protocol backplanes (e.g., RS-530A + V.35 ports on same card) without redesign or BOM proliferation. |
| V.35- and V.11-compliant impedance | Guaranteed 90–110Ω differential and 135–165Ω common-mode in V.35 mode ensures signal integrity at 40Mbps over 100Ω STP, meeting ITU-T V.35 Annex A. |
| Fast path enable/disable timing | 50µs differential-path enable and 300µs disable allow dynamic reconfiguration during link training or fault recovery without violating protocol timeouts. |
| Integrated high-voltage ESD protection | ±15kV HBM on R_A/R_B pins eliminates need for external TVS diodes in telecom line-card designs, reducing PCB area and cost. |
| Wide VL logic reference range | Supports 1.62V–5.5V VL allows direct connection to low-voltage FPGAs (1.8V) or legacy microcontrollers (5V), avoiding level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol termination applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX13175EASA+ | Same electrical specs and pinout; packaged in 38-pin SSOP (11.1mm × 10.2mm) instead of TQFN-EP. | SSOP variant suits through-hole prototyping or legacy board assemblies where TQFN reflow is unavailable. | Select MAX13175EASA+ only when manual soldering or socket-based validation is required; thermal performance (θJA = 65°C/W) is 2.3× worse than TQFN. |
| SN65LVDS31D | Single-channel LVDS driver with fixed 100Ω termination; no V.35/V.11/V.28 support, no M0–M2 configuration, no VEE rail. | Limited to point-to-point LVDS links (e.g., FPGA-to-FPGA), not multiprotocol telecom interfaces. | Use SN65LVDS31D only for LVDS-only systems; it cannot replace MAX13175EETU+ in V.35 or RS-530A applications due to missing protocol compliance and multi-channel capability. |
Compared with MAX13175EASA+, the MAX13175EETU+ offers superior thermal management and smaller footprint for high-density telecom modules; compared with SN65LVDS31D, it delivers full V.35/V.11 termination programmability, six-channel integration, and telecom-grade ESD robustness - making it irreplaceable in mixed-protocol infrastructure gear.

When paired with MAX13171E in V.35 or V.11 mode, the MAX13175EETU+ supports up to 40Mbps - verified by loopback waveforms (Figure 12, toc12) and propagation delay specs (<35ns tPLH/tPHL) across -40°C to +85°C in the MAX13171E datasheet.
How does the LATCH pin function on the MAX13175EETU+?
The LATCH pin on MAX13175EETU+ is an edge-sensitive control that freezes the current state of M0/M1/M2/DCE/DTE inputs, preventing unintended configuration changes during live data transmission. Its timing is specified as ≤12µs common-mode path enable (Table 1, p.9), ensuring glitch-free operation in synchronous systems.
Is the MAX13175EETU+ RoHS-compliant and lead-free?
Yes. The "+" suffix in MAX13175EETU+ denotes a lead(Pb)-free and RoHS-compliant package, as explicitly stated in the Ordering Information section (p.1) of the official datasheet - confirming compliance with EU Directive 2011/65/EU and JEDEC J-STD-609A Class 2a marking.
