Product details
Overview
MAX13055EEWG+T from Maxim Integrated is an 8-channel, bidirectional, high-speed logic-level translator IC designed for voltage translation between 1.62V–3.2V (VL) and 2.2V–3.6V (VCC) domains in multivoltage systems. It supports guaranteed 100Mbps data transfer with push-pull drivers, features internal 40µA pullup current sources per I/O, and operates across –40°C to +85°C. It is used in portable communication devices, camera modules, and smart card readers requiring low-power, high-fidelity level shifting.
For engineers reviewing the MAX13055EEWG+T datasheet, MAX13055EEWG+T pinout, MAX13055EEWG+T application, or MAX13055EEWG+T equivalent, key selection considerations include its 24-bump WLP package (0.4mm pitch), open-drain I/O VL_/I/O VCC_ behavior during shutdown, ±15kV HBM ESD rating, and compatibility with 4mA minimum external drivers - all critical for compact, robust, multivoltage interface design.
Technical Context
The MAX13055EEWG+T implements an nMOS pass-gate architecture with dedicated rise/fall time accelerator stages per channel, enabling sub-7ns propagation delay (tPVCC-VL/tPVL-VCC) and <2.5ns rise/fall times under 15pF load. Its dual-supply operation (VL and VCC) allows independent domain control, while automatic shutdown activates when VCC < VL - a safety feature for asymmetric power sequencing.
Each I/O pair is internally pulled up to its respective supply (VL or VCC) via 40µA current sources, eliminating need for external resistors and supporting both push-pull and open-drain drivers. The EN input provides explicit low-power control, and the device maintains defined I/O states (open-drain) during shutdown per ordering variant - confirmed for MAX13055EEWG+T in the Selector Guide.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 8 bidirectional I/O pairs - enables full parallel translation of multi-bit buses like I²C auxiliary lines or GPIO banks. |
| Max Data Rate | 100Mbps (push-pull) - supports high-speed serial links such as camera sensor control interfaces or fast peripheral handshaking. |
| Supply Range VL | +1.62V to +3.2V - matches low-voltage ASICs, FPGAs, and mobile SoCs (e.g., 1.8V core logic). |
| Supply Range VCC | +2.2V to +3.6V - interfaces directly with 3.3V system buses, PMIC rails, or legacy peripherals. |
| Propagation Delay | 1ns to 6.5ns - ensures timing-critical applications (e.g., real-time sensor sync) meet setup/hold margins. |
| ESD Rating (HBM) | ±15kV on I/O VCC_ - eliminates need for external TVS diodes in handheld device front-end interfaces. |
| Shutdown Current | 0.1µA to 2µA (VCC), 0.1µA to 4µA (VL) - enables battery-sensitive designs like GPS modules to minimize quiescent drain. |
Pinout & Package
MAX13055EEWG+T is housed in a lead-free, RoHS-compliant 24-bump Wafer-Level Package (WLP) with 0.4mm pitch. The package has no exposed pad and is optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–I/O VL8 | VL-referenced bidirectional I/O | Connect to low-voltage domain signals (e.g., 1.8V FPGA GPIO); internally pulled up to VL at 40µA. |
| I/O VCC1–I/O VCC8 | VCC-referenced bidirectional I/O | Connect to higher-voltage domain (e.g., 3.3V microcontroller bus); internally pulled up to VCC at 40µA. |
| VL | Low-voltage supply input | Bypass with 0.1µF ceramic capacitor; defines logic thresholds for VL-side I/Os. |
| VCC | High-voltage supply input | Bypass with 1µF + 0.1µF ceramics; powers VCC-side circuitry and pullups. |
| EN | Enable control input | Drive high for normal operation; drive low to enter low-power shutdown (I/Os become open-drain). |
| GND | Ground reference | Common return for both VL and VCC supplies; must be low-impedance for noise immunity. |
| N.C. | No connection | Pins 1, 12, 13, 14, 24, 25, 26, 27 - electrically unconnected; leave floating or ground per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| 8-channel bidirectional translation | Eliminates need for separate unidirectional translators or complex direction-control logic in multi-signal interfaces. |
| Internal 40µA pullup current sources | Removes external pullup resistors, saving board area and reducing BOM count in dense portable layouts. |
| Rise/fall time accelerator | Reduces edge distortion under capacitive loads (e.g., flex cables or long traces), maintaining signal integrity at 100Mbps. |
| Automatic VCC < VL shutdown | Prevents backfeeding and latch-up during asymmetric power-up sequences common in battery-powered systems. |
| ±15kV HBM ESD protection | Meets IEC 61000-4-2 Level 4 requirements without external protection components - critical for consumer-facing ports. |
Applications
| Smart Card Readers | Camera Modules |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX13056EEWG+ | I/O VCC_ pulled down to GND (10kΩ) during shutdown; same VL-side open-drain behavior. | Suitable where VCC-domain bus must be actively pulled low (e.g., reset signaling) during sleep. | Select MAX13056EEWG+ if controlled VCC-side discharge is required; otherwise MAX13055EEWG+T offers symmetric open-drain shutdown. |
| TXB0108RGER | TI part with auto-direction sensing, 3.6V max VCCA, 5.5V max VCCB, no integrated ESD protection beyond 2kV HBM. | Requires external ESD protection for handheld use; lacks guaranteed 100Mbps performance at 1.8V/3.3V. | Choose TXB0108RGER only for cost-sensitive, non-portable applications with lower ESD risk and relaxed speed requirements. |
Compared with MAX13055EEWG+T, MAX13056EEWG+ provides active VCC-side discharge during shutdown - useful for reset coordination - while TXB0108RGER trades guaranteed 100Mbps and ±15kV ESD for auto-direction convenience and wider VCCB range, but requires external protection in portable designs.

FAQ
What is the maximum data rate supported by the MAX13055EEWG+T?
The MAX13055EEWG+T guarantees 100Mbps data transfer when driven by push-pull sources. This is validated under specified conditions: VCC = +3.3V, VL = +1.8V, CI/OVCC_ ≤10pF, CI/OVL_ ≤15pF, and RSOURCE < 150Ω. Open-drain operation reduces maximum rate to 1Mbps due to RC-limited rise time - a design trade-off explicitly documented in the datasheet timing table.
Does the MAX13055EEWG+T require external pullup resistors?
No, the MAX13055EEWG+T does not require external pullup resistors. It integrates 40µA current-source pullups on all I/O VL_ and I/O VCC_ lines, enabling direct interface with both push-pull and open-drain drivers. External pullups are explicitly discouraged in the datasheet because they conflict with the internal accelerator architecture and may degrade timing or cause contention.
What happens to the I/O pins of the MAX13055EEWG+T during shutdown mode?
During shutdown (EN = GND or VCC < VL), the MAX13055EEWG+T places both I/O VL_ and I/O VCC_ pins in open-drain state - confirmed in the Ordering Information/Selector Guide for the MAX13055EEWG+T variant. This ensures high-impedance isolation without unintended DC paths, preserving signal integrity on shared buses during low-power states.
What is the ESD protection rating of the MAX13055EEWG+T?
The MAX13055EEWG+T provides ±15kV ESD protection per Human Body Model (HBM) on all I/O VCC_ pins, and ±15kV IEC 61000-4-2 air-discharge and ±8kV contact-discharge ratings. These values are measured and guaranteed - not typical - and eliminate the need for discrete ESD protection in end-equipment designs targeting IEC 61000-4-2 Level 4 compliance.
Can the MAX13055EEWG+T translate between 1.2V and 3.3V logic domains?
No, the MAX13055EEWG+T cannot translate between 1.2V and 3.3V. Its VL supply range is strictly +1.62V to +3.2V, and VCC range is +2.2V to +3.6V. A 1.2V source falls below the minimum VL specification and would fail to meet input threshold requirements (VIHL = VL – 0.2V), risking unreliable logic detection. For 1.2V interfaces, alternate translators like MAX3378E must be considered.
