Product details
Overview
MAX13046EELT+T from Maxim Integrated is a single-channel, bidirectional ±15kV ESD-protected level translator IC designed for voltage-level shifting between low-voltage (VL = +1.1V to +3.6V) and higher-voltage (VCC = +1.65V to +5.5V) domains in multivoltage systems. It uses a transmission-gate architecture to enable seamless VL ↔ VCC data translation on a single line, supports 8Mbps push-pull data rate, and features shutdown mode with <1μA supply current. It is commonly used in I²C and 1-Wire interfaces between low-power ASICs/PLDs and 3.3V/5V peripherals.
For engineers reviewing the MAX13046EELT+T datasheet, MAX13046EELT+T pinout, MAX13046EELT+T application, or MAX13046EELT+T equivalent, this page delivers verified technical context, exact pin functions, real-world timing behavior under push-pull/open-drain driving, ESD protection compliance (±15kV HBM, ±15kV IEC61000-4-2 air-gap), and validated alternatives for I²C/1-Wire level-shifting designs requiring sub-1μA shutdown and rail-to-rail bidirectional operation.
Technical Context
The MAX13046EELT+T implements a transmission-gate-based bidirectional level shifter with integrated rise-time accelerators on both VL and VCC sides, enabling guaranteed 8Mbps (up to 16Mbps under +1.8V ≤ VL ≤ VCC ≤ +3.3V) push-pull operation. Its internal 10kΩ pullup resistors on I/O VL and I/O VCC support open-drain configurations without external components.
It features thermal short-circuit protection that triggers shutdown at TJ > +150°C and auto-resumes above +140°C. The SHDN input controls device enable/disable, disconnecting internal pullups and forcing I/O into high-impedance state - critical for multidrop bus architectures and power sequencing where VL or VCC may be unpowered.
Key Specifications

Pinout & Package
The MAX13046EELT+T is housed in a 6-pin μDFN package (1.0mm × 1.5mm, 0.5mm pitch), RoHS-compliant and optimized for space-constrained portable PCBs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VL | Low-voltage supply input; must be bypassed with 0.1µF ceramic capacitor near pin for stable operation |
| 2 | GND | Ground reference for both VL and VCC domains; shared return path for bidirectional signal integrity |
| 3 | I/O VL | Bidirectional data terminal referenced to VL; connects to low-voltage side (e.g., 1.2V/1.8V microcontroller I/O) |
| 4 | I/O VCC | Bidirectional data terminal referenced to VCC; connects to higher-voltage side (e.g., 3.3V/5V peripheral bus) |
| 5 | SHDN | Active-high enable input; drives low to enter <1μA shutdown, isolating I/O lines and disabling internal pullups |
| 6 | VCC | High-voltage supply input; requires 1µF ceramic capacitor for full ±15kV ESD protection per datasheet Note 4 |
Key Features
| Feature | Design Value |

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 | 2-channel, 1.65V–5.5V dual-supply, no integrated ESD protection beyond standard HBM (±2kV), no rise-time accelerator | Lacks ±15kV IEC61000-4-2 rated ESD protection; requires external TVS for rugged environments | Prefer TXS0102DCUR only when cost sensitivity outweighs ESD robustness and multi-channel integration is needed |
| PCA9306DP | 2-channel, 1.2V–5.5V, open-drain only, no push-pull support, no shutdown mode, no thermal protection | Cannot support push-pull I²C Fast-mode Plus (1Mbps+) or 1-Wire without external pullups and lacks fail-safe shutdown | Select PCA9306DP only for simple, low-speed, non-rugged open-drain applications where shutdown and ESD are not required |
Compared with TXS0102DCUR and PCA9306DP, the MAX13046EELT+T uniquely combines single-channel simplicity, ±15kV system-level ESD immunity, sub-1μA shutdown, and 16Mbps push-pull capability - making it the only choice for space-constrained, battery-powered, and field-deployed I²C/1-Wire designs demanding full IEC61000-4-2 compliance.

FAQ
What is the maximum capacitive load the MAX13046EELT+T can drive while maintaining 8Mbps operation?
The MAX13046EELT+T maintains guaranteed 8Mbps push-pull operation with ≤15pF total load capacitance (including PCB trace and device pin capacitance), as characterized in the datasheet under typical conditions (VCC = +3.3V, VL = +1.8V, CL = 15pF). Driving >20pF increases rise/fall times nonlinearly and may reduce effective data rate below specification - verify with oscilloscope measurements on actual board layout.
Does the MAX13046EELT+T require external pullup resistors for I²C operation?
No - the MAX13046EELT+T integrates 10kΩ pullup resistors on both I/O VL and I/O VCC pins, eliminating external pullups for standard I²C open-drain operation. These resistors are automatically disconnected in shutdown mode (SHDN = low), preserving bus integrity in low-power states. External pullups are only needed if stronger drive strength or custom voltage thresholds are required.
Can the MAX13046EELT+T translate between VL = +1.1V and VCC = +5.5V reliably?
Yes - the MAX13046EELT+T is explicitly specified for VL as low as +1.1V and VCC as high as +5.5V, provided VL ≤ min(+3.6V, VCC + 0.3V). At this extreme combination, the guaranteed data rate drops to 8Mbps (push-pull), and output voltage levels meet VOHL = 0.67×VL and VOHC = 0.67×VCC, ensuring compatible logic thresholds with downstream receivers.
How does shutdown mode affect I/O pin states on the MAX13046EELT+T?
In shutdown mode (SHDN = low), the MAX13046EELT+T disables internal 10kΩ pullup resistors and places both I/O VL and I/O VCC pins in high-impedance state. This allows safe multidrop bus operation and prevents contention. However, absolute maximum ratings still apply: I/O VL must not exceed (VL + 0.3V), and I/O VCC must not exceed (VCC + 0.3V), even in shutdown.
Is the MAX13046EELT+T compatible with 1-Wire bus timing requirements?
Yes - the MAX13046EELT+T supports 1-Wire level translation with verified performance up to 16.3kbps (e.g., with DS2502 EEPROM), meeting standard 1-Wire timing margins. Its sub-30ns propagation delay and rise-time accelerator ensure reliable pulse edge fidelity. A 5kΩ external pullup is recommended on the 1-Wire bus side per Maxim's application guidance.
