Product details
Overview
MAX3393EEBC-T from Maxim Integrated is a quad unidirectional voltage-level translator IC enabling bidirectional signal translation between 1.2V–5.5V logic domains, supporting up to 16Mbps data rate at +1.8V/+2.5V supply pairs, featuring ±15kV HBM ESD protection on VCC-side I/Os, 1µA three-state quiescent current, and operation in TDFN-14 (3mm × 3mm) package for portable communication and smart card reader applications.
For engineers reviewing the MAX3393EEBC-T datasheet, MAX3393EEBC-T pinout, MAX3393EEBC-T application, or MAX3393EEBC-T equivalent, this page delivers verified electrical specs, real-world timing behavior across voltage domains, thermal short-circuit protection details, and validated alternative parts for SPI/I²C level-shifting designs requiring robust ESD immunity and low-power standby.
Technical Context
The MAX3393EEBC-T implements unidirectional level translation (VL → VCC only) using MOSFET-based pass-gate architecture with integrated speed-up circuitry-dual one-shot generators reduce rise time via temporary pull-up activation during low-to-high transitions. It supports independent VL (+1.2V to +5.5V) and VCC (+1.65V to +5.5V) supplies, with logic thresholds referenced to respective rails (VIHL = VL − 0.2V, VIHC = VCC − 0.4V).
Three-state control is VL-referenced: pulling THREE-STATE low disables internal 10kΩ pullups and places all I/Os in high-impedance mode, reducing total supply current to <1µA. Thermal shutdown activates at TJ = +152°C and recovers at +142°C, protecting against sustained output shorts without latchup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VL) | +1.2V to +5.5V - enables interface with ultra-low-voltage ASICs, PLDs, and battery-powered controllers. |
| Supply Range (VCC) | +1.65V to +5.5V - supports legacy 3.3V/5V systems while maintaining compatibility with modern 1.8V interfaces. |
| Max Data Rate | 16Mbps at +1.8V ≤ VL ≤ VCC ≤ +2.5V - enables high-speed SPI clocking without external buffers in compact portable designs. |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for discrete TVS diodes in handheld device I/O routing. |
| Three-State Current | <1µA - allows deep-sleep power management in battery-operated POS terminals and GPS modules. |
| Propagation Delay | 15ns typical (VL ↔ VCC, +2.5V domain) - ensures timing margin for 33MHz SPI master/slave handshaking. |
| Output Drive Strength | VOHL = 0.67×VL, VOLC = 0.4V - guarantees rail-to-rail logic swing into 1mA loads, compatible with CMOS inputs across voltage domains. |
Pinout & Package
TDFN-14 (3mm × 3mm, exposed pad), RoHS-compliant, thermally enhanced package with 0.5mm pitch; pin 1 marked by dot, EP connected to GND for optimal thermal dissipation and noise immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 14) | High-side supply input | Power rail for VCC-referenced I/Os; must be ≥ VL and ≤ (VL + 0.3V) during normal operation. |
| VL (Pin 7) | Low-side supply input | Reference for VL-referenced I/Os and THREE-STATE logic threshold; sets VIHL/VILL levels. |
| THREE-STATE (Pin 6) | Enable control input | VL-referenced active-low signal; drives all I/Os into high-Z when pulled low, disabling internal pullups. |
| GND (Pin 4) | Ground reference | Common return path for both supply domains; EP must be soldered to GND plane for thermal compliance. |
| I/O VL1–VL4 (Pins 2,3,5,10) | Low-voltage bidirectional I/Os | Accept 1.2V logic; drive 0.67×VL high / 0.4V low into 20µA/1mA loads; not internally connected to VCC side. |
| I/O VCC1–VCC4 (Pins 1,8,9,13) | High-voltage unidirectional outputs | Translate VL-side signals to VCC logic levels only; cannot drive VL side - true unidirectional flow. |
| N.C. (Pins 11,12) | No connection | Not bonded; must remain floating - no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Rise-time acceleration circuitry | Dual one-shot generators cut tRVCC/tRVL by >50% vs. passive translators, enabling 16Mbps operation without external active termination. |
| Thermal short-circuit protection | Auto-entry to three-state mode at +152°C junction temperature prevents permanent damage during sustained I/O faults. |
| ±15kV HBM ESD on VCC I/Os | Guaranteed survival of direct human-hand discharge events without functional degradation or latchup - validated per JEDEC JS-001. |
| 1µA three-state supply current | Enables zero-power bus isolation in multi-drop SPI configurations where devices share MISO/MOSI lines. |
| VL-referenced THREE-STATE logic | Eliminates level-shifter dependency on VCC for control signaling - simplifies power sequencing in mixed-rail systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0104RUTR | Auto-direction sensing, 1.2V–3.6V I/O range, no VCC/VL separation - single-supply operation only. | Requires no THREE-STATE control but lacks ±15kV ESD rating and thermal shutdown. | Select when system uses uniform 1.8V/2.5V rails and ESD exposure is minimal; avoid in connector-facing designs. |
| SN74AVC4T245PW | 3.6V max VCC, 1.2V–3.6V I/O, 3.5ns tPD, no integrated ESD beyond standard HBM. | Higher speed but requires external ±15kV TVS diodes on exposed lines - increases PCB area and cost. | Choose for ultra-low-latency applications where board space permits discrete protection and thermal monitoring is handled externally. |
Compared with TXB0104RUTR and SN74AVC4T245PW, the MAX3393EEBC-T uniquely combines guaranteed 16Mbps operation at 1.8V/2.5V, integrated thermal fault recovery, and ±15kV HBM-rated VCC I/Os - making it optimal for space-constrained, user-accessible portable electronics where reliability under ESD stress is non-negotiable.

FAQ
What is the maximum guaranteed data rate for MAX3393EEBC-T across all voltage combinations?
The MAX3393EEBC-T guarantees 8Mbps operation for all valid VL/VCC combinations from +1.2V to +5.5V. At narrower ranges - specifically +1.8V ≤ VL ≤ VCC ≤ +2.5V and +2.5V ≤ VL ≤ VCC ≤ +3.3V - it achieves 16Mbps. These higher rates are validated per the Timing Characteristics table and require CLOAD ≤ 15pF and driver impedance ≤ 50Ω.
Can MAX3393EEBC-T translate signals from VCC to VL, or is it strictly VL-to-VCC?
The MAX3393EEBC-T is a unidirectional level translator configured exclusively for VL → VCC translation. Its internal architecture does not support reverse flow (VCC → VL). For bidirectional translation, consider the MAX3377E or MAX3378E variants within the same family.
How does the THREE-STATE pin function, and what happens to I/O states during three-state mode?
The THREE-STATE pin is VL-referenced and active-low. When pulled low, it disables internal 10kΩ pullup resistors on all I/O VCC_ and I/O VL_ lines, placing them in high-impedance state. Supply current drops to <1µA. During this mode, I/O voltages must remain within (VL + 0.3V) and (VCC + 0.3V) limits to prevent damage.
Does MAX3393EEBC-T include thermal protection, and how does it behave during overload?
Yes, MAX3393EEBC-T integrates thermal short-circuit protection. When junction temperature reaches +152°C, it automatically forces entry into three-state mode, disconnecting I/Os and reducing power dissipation. Normal operation resumes once TJ cools to +142°C - no reset or power cycle required.
Is external capacitor required for ESD protection, and if so, where should it be placed?
A 1µF capacitor between VCC and GND is recommended to maximize ESD protection effectiveness per Maxim's application guidance. This decoupling capacitor stabilizes the VCC rail during fast ESD transients and ensures the ±15kV HBM rating is fully realized in end-equipment layouts.
