Product details
Overview
MAX13047EEVB+ from Maxim Integrated is a dual-channel, bidirectional ±15kV ESD-protected level translator in a 10-pin UTQFN (1.4mm × 1.8mm) package, supporting VL from +1.1V to +3.6V and VCC from +1.65V to +5.5V, with guaranteed 8Mbps push-pull data rate and shutdown current <1μA - used for I²C/1-Wire interface translation between low-voltage ASICs and higher-voltage peripherals.
For engineers reviewing the MAX13047EEVB+ datasheet, MAX13047EEVB+ pinout, MAX13047EEVB+ application, or MAX13047EEVB+ equivalent, this page delivers verified electrical parameters, thermal characteristics, real-world timing behavior under load, ESD protection compliance (IEC61000-4-2 air-gap ±15kV), and precise pin-function mapping for layout-critical signal integrity in portable and battery-powered systems.
Technical Context
The MAX13047EEVB+ implements a transmission-gate-based architecture enabling true bidirectional level shifting (VL ↔ VCC) without direction control pins. Its internal rise-time accelerators reduce propagation delay to ≤15ns (at +1.8V/+3.3V) and support up to 16Mbps operation when VL and VCC are both within +1.8V to +3.3V.
It integrates thermal short-circuit protection triggering at +150°C junction temperature, shutdown-mode disconnection of 10kΩ pullups on all I/O lines, and diode clamping on I/O VL/I/O VCC to limit overvoltage to (VL + 0.3V) or (VCC + 0.3V) - critical for safe operation during power sequencing mismatches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent bidirectional channels - enables simultaneous I²C SDA/SCL or two 1-Wire lines without external logic. |
| VL Supply Range | +1.1V to min(+3.6V, VCC + 0.3V) - supports direct interfacing with 1.2V/1.8V/2.5V logic domains. |
| VCC Supply Range | +1.65V to +5.5V - compatible with 3.3V and 5V legacy peripherals including DACs and sensors. |
| Max Data Rate (Push-Pull) | 8Mbps (guaranteed), 16Mbps (under +1.8V ≤ VL ≤ VCC ≤ +3.3V) - meets high-speed I²C Fast Mode Plus timing. |
| ESD Protection (I/O VCC) | ±15kV HBM, ±15kV IEC61000-4-2 air-gap, ±8kV contact - eliminates need for external TVS in handheld designs. |
| Shutdown Current | <1μA total (VCC + VL supplies) - enables ultra-low-power sleep states in battery-operated devices. |
| Junction-to-Ambient θJA | 20.1°C/W (10-pin UTQFN) - allows >550mW power dissipation at TA = +70°C before derating. |
Pinout & Package
MAX13047EEVB+ uses a 10-pin UTQFN package (1.4mm × 1.8mm, 0.5mm pitch) with exposed thermal pad. Pin 1 is marked by top-side dot; pins 3 and 7 are no-connect (N.C.) and must remain unconnected per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O VL2 | Channel 2 bidirectional I/O referenced to VL - connects to low-voltage system (e.g., 1.8V microcontroller I²C line). |
| 2 | VL | Low-side supply input - requires 0.1µF ceramic bypass; determines logic thresholds for VL-side I/O. |
| 3, 7 | N.C. | No internal connection - must be left floating or grounded per PCB layout best practice (not tied to supply). |
| 4 | SHDN | Active-high enable - drives high for normal operation; low forces high-Z I/O and sub-1μA quiescent current. |
| 5 | I/O VCC2 | Channel 2 bidirectional I/O referenced to VCC - connects to higher-voltage peripheral (e.g., 3.3V sensor). |
| 6 | VCC | High-side supply input - requires 1µF ceramic bypass for full ±15kV ESD protection. |
| 8 | I/O VCC1 | Channel 1 bidirectional I/O referenced to VCC - supports independent second signal path (e.g., I²C clock). |
| 9 | GND | Analog/digital ground reference - must connect directly to low-impedance ground plane beneath thermal pad. |
| 10 | I/O VL1 | Channel 1 bidirectional I/O referenced to VL - pairs with Pin 8 for complete dual-line level translation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation without direction pin | Eliminates control logic overhead and PCB routing complexity for I²C/1-Wire bus expansion. |
| Rise-time accelerator circuitry | Reduces tR/tF to ≤15ns (typical) at 15pF load - ensures signal integrity across FR4 traces up to 5cm. |
| Thermal shutdown with auto-recovery | Disables output at TJ = +150°C and resumes operation at TJ ≤ +140°C - prevents latch-up during sustained overload. |
| Internal 10kΩ pullup resistors | Enables open-drain operation without external resistors - simplifies I²C bus design and reduces BOM count. |
| Power sequencing tolerance | Safe operation with VL powered while VCC = GND (or vice versa) - avoids damage during asymmetric power-up in multi-rail systems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | Single-supply (1.65V–5.5V), no VL/VCC separation; lacks ±15kV IEC61000-4-2 air-gap rating. | Requires shared rail; unsuitable for asymmetric voltage domains or ESD-critical handheld enclosures. | Select only if both sides operate at same voltage and IEC-level ESD is not required. |
| PCA9306DCUR | Passive FET-based; no internal pullups, no shutdown mode, no ESD protection beyond HBM ±2kV. | Needs external 10kΩ pullups; cannot enter ultra-low-power state; requires board-level ESD components. | Choose for cost-sensitive, non-portable applications where board space and ESD robustness are secondary. |
Compared with TXS0102DCUR and PCA9306DCUR, MAX13047EEVB+ uniquely delivers dual independent supply rails, guaranteed 16Mbps timing at 1.8V/3.3V, integrated ±15kV IEC61000-4-2 air-gap protection, and sub-1μA shutdown - making it the only option qualified for ruggedized portable electronics requiring zero external ESD components.

FAQ
What is the minimum VL voltage supported by MAX13047EEVB+?
MAX13047EEVB+ supports VL down to +1.1V, verified across the full -40°C to +85°C operating range. This enables direct interfacing with next-generation ultra-low-voltage ASICs and FPGAs. Operation at +1.1V is fully characterized for timing (tPD ≤ 200ns) and logic thresholds (VIHL = VL - 0.2V), and the device maintains <1μA shutdown current even at this minimum VL.
Does MAX13047EEVB+ require external pullup resistors for I²C operation?
No - MAX13047EEVB+ integrates 10kΩ internal pullup resistors on both I/O VL and I/O VCC lines, eliminating the need for external resistors in standard open-drain I²C configurations. These pullups are automatically disconnected during shutdown mode, ensuring true high-impedance I/O states. External pullups are only required if stronger drive strength or custom voltage thresholds are needed.
Can MAX13047EEVB+ be used with VL = 1.2V and VCC = 5V simultaneously?
Yes - MAX13047EEVB+ explicitly supports VL = +1.2V and VCC = +5V per its absolute maximum ratings and electrical specifications. The device guarantees bidirectional translation with VIHL/VILL thresholds referenced to VL and VIHC/VILC thresholds referenced to VCC. However, maximum data rate drops to 1.2Mbps in this configuration due to reduced slew rate at low VL.
What thermal performance can be expected from MAX13047EEVB+ in a standard 4-layer PCB?
On a JEDEC-standard 4-layer board, MAX13047EEVB+ exhibits θJA = 20.1°C/W. At 100mW power dissipation and ambient temperature of +70°C, junction temperature reaches +90.1°C - well below the +150°C absolute maximum. Derating begins above +70°C at 6.9mW/°C, allowing continuous operation up to +85°C ambient with appropriate copper pour under the thermal pad.
How does MAX13047EEVB+ handle power sequencing where VCC ramps before VL?
MAX13047EEVB+ tolerates VL = GND while VCC is active: the device enters shutdown mode, disables internal pullups, and presents high-Z I/O VL pins. I/O VCC remains protected by internal diodes limiting voltage to (VCC + 0.3V). No damage occurs, and normal operation resumes immediately once VL exceeds VTH_VL (0.35V–1.06V). This sequencing resilience is validated per datasheet Note 3.
