Product details
Overview
MAX3392EEBC from Maxim Integrated is a quad bidirectional ±15kV ESD-protected level translator enabling voltage translation between 1.2V–5.5V logic domains (VL) and 1.65V–5.5V systems (VCC). It supports guaranteed 8Mbps data rate across full voltage range, delivers rail-to-rail output swing, features ultra-low 1µA three-state supply current, and operates in TDFN-14 (3mm × 3mm) package for space-constrained portable communication interfaces.
For engineers reviewing the MAX3392EEBC datasheet, MAX3392EEBC pinout, MAX3392EEBC application, or MAX3392EEBC equivalent, this device is selected for low-voltage ASIC-to-processor interfacing where bidirectional SPI/I²C signal translation, ESD-hardened external routing, and dynamic power gating via THREE-STATE control are required.
Technical Context
The MAX3392EEBC uses a transmission-gate-based architecture to enable true bidirectional level shifting (VL ↔ VCC) on all four channels without direction-control pins. Its internal speed-up circuitry-comprising one-shot-triggered pull-up MOSFETs (PU1/PU2)-reduces rise time and propagation delay for low-to-high transitions, enabling operation up to 16Mbps under specific voltage/load conditions (+1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V).
Three-state mode is controlled by a VL-referenced input that disables internal 10kΩ pullups and places all I/O lines in high-impedance state, reducing total supply current to <1µA. Thermal short-circuit protection activates at +152°C junction temperature, forcing automatic entry into three-state mode until cooling to +142°C.
Key Specifications

|---|---|
| Supply Range VL | +1.2V to +5.5V - enables interface with sub-1.8V ASICs, PLDs, and battery-powered logic |
| Supply Range VCC | +1.65V to +5.5V - supports legacy 3.3V/5V systems and modern low-power microcontrollers |
| Guaranteed Data Rate | 8Mbps over full voltage range - ensures reliable timing margin for high-speed serial buses like SPI |
| ESD Protection (I/O VCC) | ±15kV HBM - eliminates need for external TVS diodes on externally routed signal lines |

| Output Voltage Swing | 0.67×VL / 0.67×VCC - provides rail-aligned logic thresholds compatible with CMOS inputs |
Pinout & Package
MAX3392EEBC is housed in a 14-pin TDFN package (3mm × 3mm, 0.5mm pitch) with exposed pad (EP) for thermal enhancement and grounding. Pin functions are VL-referenced for control signals and dual-supply referenced for I/O pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 14) | High-side supply input | Power domain for I/O VCCx outputs; must be ≥1.65V and ≤5.5V |
| VL (Pin 7) | Low-side supply input | Power domain and logic reference for I/O VLx and THREE-STATE control |
| THREE-STATE (Pin 6) | Three-state enable input | Pull low to disable all I/Os; logic-high threshold = VL − 0.2V |
| GND (Pin 4) | Ground reference | Common return path for both supply domains and thermal pad connection point |
| I/O VL1–VL4 (Pins 2,3,5,8) | Bidirectional low-voltage I/O | Signal translation endpoints referenced to VL; tolerate −0.3V to (VL + 0.3V) |
| I/O VCC1–VCC4 (Pins 1,12,11,10) | Bidirectional high-voltage I/O | Signal translation endpoints referenced to VCC; tolerate −0.3V to (VCC + 0.3V) |
| EP (Exposed Pad) | Thermal & electrical ground | Must be soldered to PCB ground plane for thermal regulation and EMI reduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0104RUTR | Auto-direction sensing; no THREE-STATE pin; 1.2V–3.6V VL, 1.65V–5.5V VCC; 100Mbps max (open-drain) | Requires no direction-control logic but lacks thermal shutdown and has lower ESD rating (±8kV HBM) | Select when auto-bidirectional operation is prioritized over ESD robustness and fault tolerance |
| SN74AVC4T245PW | Direction-controlled (DIR pin); 1.2V–3.6V A/B sides; 32mA drive strength; no integrated ESD beyond standard HBM | Higher drive capability suits longer traces but requires external ±15kV protection for exposed interfaces | Select when high-current bus driving is needed and external ESD protection is acceptable |

FAQ
What is the maximum data rate supported by the MAX3392EEBC under typical operating conditions?
The MAX3392EEBC guarantees 8Mbps operation across its full specified voltage range (+1.2V ≤ VL ≤ VCC ≤ +5.5V). Under optimized conditions-specifically +1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V with ≤50pF load-the MAX3392EEBC achieves up to 16Mbps, as confirmed in the Timing Characteristics table of its official datasheet.
Does the MAX3392EEBC require external pull-up resistors on its I/O lines?
No. The MAX3392EEBC integrates internal 10kΩ pull-up resistors on both I/O VLx and I/O VCCx lines during normal operation. These are automatically disconnected when the THREE-STATE pin is pulled low, placing all I/Os in high-impedance mode. External pull-ups are unnecessary unless specific bus topology requirements dictate otherwise.
How does the thermal short-circuit protection function in the MAX3392EEBC?
The MAX3392EEBC monitors junction temperature and forces automatic entry into three-state output mode when TJ reaches +152°C. This disconnects all I/Os and reduces supply current to <1µA, allowing thermal dissipation. Normal operation resumes autonomously once TJ cools to +142°C-no external reset or power cycle is required.
Can the MAX3392EEBC translate signals between 1.2V and 5.5V logic domains?
Yes. The MAX3392EEBC accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, supporting translation between ultra-low-voltage logic (e.g., 1.2V FPGA I/O) and legacy 5V systems. However, VL must not exceed (VCC + 0.3V) during steady-state operation per Absolute Maximum Ratings.
Is the MAX3392EEBC pin-compatible with other devices in the MAX3372E–MAX3379E/MAX3390E–MAX3393E family?
Yes. The MAX3392EEBC shares identical pinout and footprint with MAX3377E, MAX3378E, and MAX3379E in the 14-pin TDFN package. All share the same VL/VCC dual-supply architecture, THREE-STATE control, and bidirectional I/O structure-enabling drop-in replacement within the same package variant.
