Product details
Overview
The MAX3390EEBC from Maxim Integrated is a quad unidirectional voltage-level translator IC enabling bidirectional data flow across two independent logic domains (VL and VCC), supporting 1.2V to 5.5V VL and 1.65V to 5.5V VCC supplies, guaranteed 8Mbps operation over full voltage range, ±15kV HBM ESD protection on VCC-side I/Os, and ultra-low 1µA three-state supply current - used in SPI/MICROWIRE/I²C interfaces between low-voltage ASICs and higher-voltage peripherals.
For engineers reviewing the MAX3390EEBC datasheet, MAX3390EEBC pinout, MAX3390EEBC application, or MAX3390EEBC equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world timing behavior at 1.8V/3.3V, thermal short-circuit protection details, and direct alternative part comparisons for multivoltage system design.
Technical Context
The MAX3390EEBC implements unidirectional level translation (VL → VCC only) using MOSFET-based pass-gate architecture with integrated speed-up circuitry - a one-shot-triggered pull-up accelerator that reduces tR/tF and propagation delay for low-to-high transitions. It does not support bidirectional translation like MAX3377E/MAX3378E.
Its four independent channels each feature separate VL-referenced inputs (I/O VL1–VL4) and VCC-referenced outputs (I/O VCC1–VCC4), with dedicated THREE-STATE control referenced to VL. Logic thresholds are adaptive: VIHL = VL − 0.2V, VIHC = VCC − 0.4V, ensuring robust noise margins across operating voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VL) | +1.2V to +5.5V - enables interface with 1.2V/1.8V/2.5V/3.3V/5V logic families |
| Supply Range (VCC) | +1.65V to +5.5V - supports legacy 5V systems while maintaining compatibility with modern low-VCC rails |
| Max Data Rate | 8Mbps over full VL/VCC range - sufficient for high-speed SPI clocking up to ~4MHz SCLK with margin |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in handheld/portable designs |
| Three-State Current | <1µA (typ 0.03µA) - enables true low-power sleep mode in battery-powered devices |
| Propagation Delay | 190–1000ns (open-drain, CL=15pF) - predictable timing for synchronous protocol alignment |
| Channel Skew | 50ns max (open-drain) - ensures simultaneous channel enable/disable in quad-bus applications |
Pinout & Package
MAX3390EEBC is packaged in a 14-pin TDFN (3mm × 3mm) with exposed pad, pin-compatible with MAX3377E/MAX3378E/MAX3379E and other quad translators in the family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–VL4 | Low-voltage side input/output | VL-referenced signal terminals; accept 1.2V–5.5V logic; drive internal pass gates |
| I/O VCC1–VCC4 | High-voltage side output | VCC-referenced outputs only (unidirectional VL→VCC); swing rail-to-rail (0.67×VCC min) |
| VL | Low-voltage supply reference | Defines logic thresholds and THREE-STATE input levels; must be ≤ VCC + 0.3V |
| VCC | High-voltage supply reference | Powers output stage and ESD protection; accepts 1.65V–5.5V |
| THREE-STATE | Enable control input | Pull low (to GND) to tri-state all I/Os; referenced to VL logic levels (VIH = VL−0.2V) |
| GND | Ground reference | Common return for both supplies; exposed pad must be soldered to PCB ground plane |
| N.C. | No connection | Pins 6 and 9 - internally unconnected; leave floating or ground per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional VL→VCC translation | Eliminates bus contention risk in master-slave SPI configurations where direction is fixed |
| Rise-time acceleration circuitry | Reduces tR to 15–40ns at 1.8V/2.5V/3.3V - enables 10–16Mbps operation within voltage-limited domains |
| Thermal short-circuit protection | Auto-triggers three-state mode at TJ = +152°C; resumes at +142°C - prevents latch-up during sustained overload |
| 1µA three-state quiescent current | Enables zero-power bus isolation in portable POS or GPS receivers during standby |
| 14-pin TDFN (3×3mm) with EP | 0.5mm pitch, 0.75mm height - suitable for space-constrained mobile PCBs with thermal relief via exposed pad |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3379EEBE+ | Same quad unidirectional architecture, identical pinout (14-pin TDFN), but rated for 230kbps only - no rise-time accelerator | Targeted at low-speed I²C or MICROWIRE; unsuitable for 8Mbps SPI | Select MAX3379EEBE+ only when data rate ≤230kbps and cost sensitivity outweighs performance needs |
| TXS0104EPWR | TI quad unidirectional translator; 1.65–5.5V VCCA/VCCB; 60Mbps max; no integrated ESD - requires external ±8kV protection | Higher speed but adds BOM complexity; lacks thermal shutdown and 1µA three-state | Choose TXS0104EPWR only if >8Mbps is required and external ESD + thermal management is acceptable |
Compared with MAX3379EEBE+, MAX3390EEBC delivers 35× higher guaranteed data rate and integrated speed-up circuitry; versus TXS0104EPWR, it trades raw speed for robustness - delivering ±15kV ESD, thermal protection, and sub-1µA quiescent current in the same footprint.

FAQ
What is the maximum guaranteed data rate for MAX3390EEBC across its full operating voltage range?
The MAX3390EEBC guarantees 8Mbps operation for all combinations of VL (1.2V–5.5V) and VCC (1.65V–5.5V). Higher rates - up to 16Mbps - are achievable within narrower voltage windows (e.g., +1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V), as confirmed in the Timing Characteristics table of the official datasheet.
Does MAX3390EEBC support bidirectional level translation like the MAX3377E?
No. The MAX3390EEBC is strictly unidirectional (VL → VCC only), unlike the bidirectional MAX3377E. Its internal architecture uses dedicated input (I/O VLx) and output (I/O VCCx) terminals with no feedback path - making it unsuitable for I²C open-drain bus applications requiring automatic direction sensing.
How does the THREE-STATE pin function on MAX3390EEBC, and what logic levels activate it?
The THREE-STATE pin on MAX3390EEBC is VL-referenced: pulling it low (≤0.15V) places all I/O VCC and I/O VL pins in high-impedance state, reducing total supply current to <1µA. To enable normal operation, connect THREE-STATE to VL (logic high ≥ VL − 0.2V). It is not VCC-referenced and must never exceed VL + 0.3V.
Can MAX3390EEBC safely interface a 1.2V FPGA I/O bank with a 5V peripheral without external components?
Yes. The MAX3390EEBC accepts VL = +1.2V and VCC = +5.0V, translating signals with VOHC = 0.67 × VCC = 3.35V (min) and VOLC = 0.4V (max) - compatible with standard 5V TTL input thresholds. Its ±15kV HBM ESD rating on I/O VCC pins eliminates need for external protection diodes in most handheld or docked applications.
What thermal protection mechanism does MAX3390EEBC implement, and at what junction temperature does it trigger?
The MAX3390EEBC integrates thermal short-circuit protection that monitors die temperature. When junction temperature reaches +152°C, it automatically forces the device into three-state output mode. Normal operation resumes once the junction cools to +142°C - preventing permanent damage during sustained overload or PCB trace shorts.
