Product details
Overview
The MAX3393EEBC+T from Maxim Integrated is a quad unidirectional logic-level translator enabling voltage-domain bridging between low-voltage (VL = +1.2V to +5.5V) and higher-voltage (VCC = +1.65V to +5.5V) digital systems. It supports guaranteed 8Mbps data rate across full voltage range, delivers ±15kV HBM ESD protection on VCC-side I/Os, features three-state output control, and operates with quiescent current as low as 130µA - ideal for SPI/I²C interface translation in portable POS and smart card readers.
For engineers reviewing the MAX3393EEBC+T datasheet, MAX3393EEBC+T pinout, MAX3393EEBC+T application, or MAX3393EEBC+T equivalent, key selection criteria include its 4-channel unidirectional architecture, VL/VCC supply independence, 1μA three-state supply current, slew-rate-limited outputs for EMI reduction, and compatibility with 1.2V–3.3V/1.65V–3.3V mixed-signal interconnects.
Technical Context
The MAX3393EEBC+T implements four independent unidirectional level-shifting channels using MOSFET-based pass-gate topology with integrated speed-up circuitry. Each channel translates signals strictly VL → VCC (or VCC → VL per pin configuration), with input thresholds referenced to respective supplies (VIHL = VL − 0.2V, VIHC = VCC − 0.4V) and rail-to-rail output drive capability (VOHL = 0.67×VL, VOHC = 0.67×VCC).
It integrates thermal short-circuit protection that forces automatic entry into three-state mode at TJ = +152°C and auto-resumes operation at +142°C. The device requires no external components for basic operation but benefits from a 1µF VCC-to-GND capacitor to maximize ESD robustness per IEC 1000-4-2 compliance guidance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0104RUTR | Auto-direction sensing; 1.2V–3.6V I/O range; no THREE-STATE pin; 100Mbps max (but only 10Mbps guaranteed) | Requires no direction-control signal; unsuitable where explicit three-state bus management is needed | Select when bidirectional auto-sensing is preferred and VL/VCC overlap is tight (e.g., 1.8V ↔ 3.3V only) |
| SN74AVC4T245PWR | Bus-hold circuitry; 1.2V–3.6V; 3.6V-tolerant I/Os; 3-state enabled by OE pin; 32mA drive strength | Higher drive capability suits longer traces; lacks ±15kV HBM rating - requires external ESD protection | Select for industrial environments with long trace lengths or where higher noise immunity is required |
Compared with TXB0104RUTR and SN74AVC4T245PWR, the MAX3393EEBC+T provides superior ESD robustness (±15kV HBM), deterministic unidirectional control via dedicated THREE-STATE pin, and guaranteed 8Mbps performance across wider VL/VCC combinations - making it optimal for consumer-grade portable interfaces where reliability and supply flexibility are critical.

FAQ
What is the maximum data rate supported by the MAX3393EEBC+T?
The MAX3393EEBC+T guarantees 8Mbps operation across its full specified VL (+1.2V to +5.5V) and VCC (+1.65V to +5.5V) supply ranges. Under specific conditions - such as VL/VCC = 1.8V/2.5V or 2.5V/3.3V with CLOAD ≤ 15pF - it achieves up to 16Mbps, as confirmed in the Timing Characteristics table of the official datasheet. This makes the MAX3393EEBC+T suitable for high-speed SPI and MICROWIRE interfaces in portable devices.
Does the MAX3393EEBC+T support bidirectional level translation?
No, the MAX3393EEBC+T is a unidirectional level translator. Per the datasheet, it supports translation in one direction per channel - either VL → VCC or VCC → VL - depending on pin assignment. Bidirectional operation requires devices like the MAX3377E or MAX3378E from the same family. The MAX3393EEBC+T's four independent channels are configured for fixed-direction translation, controlled externally via signal routing.
How does the THREE-STATE pin function on the MAX3393EEBC+T?
The THREE-STATE pin on the MAX3393EEBC+T is an active-low control input referenced to VL. Pulling it low places all eight I/O pins (I/O VL1–VL4 and I/O VCC1–VCC4) into high-impedance state and reduces total supply current to less than 1µA. For normal operation, connect THREE-STATE to VL. This feature enables dynamic bus isolation in multi-drop configurations - essential for shared SPI or I²C buses where multiple peripherals share signal lines.
What ESD protection level does the MAX3393EEBC+T provide?
The MAX3393EEBC+T provides ±15kV Human Body Model (HBM) ESD protection on all VCC-side I/O pins (I/O VCC1–VCC4), as verified per JEDEC JS-001. It also meets ±8kV IEC 1000-4-2 contact discharge and ±10kV air-gap discharge requirements. This eliminates the need for external TVS diodes in handheld and portable applications - a key differentiator versus standard translators like the SN74LVC4T245.
Can the MAX3393EEBC+T operate with VL = 1.2V and VCC = 5.5V simultaneously?
Yes, the MAX3393EEBC+T is explicitly rated for VL = +1.2V to +5.5V and VCC = +1.65V to +5.5V, with the constraint VL ≤ (VCC + 0.3V). Since 1.2V ≤ (5.5V + 0.3V), this combination is fully supported. The device maintains guaranteed 8Mbps performance and correct logic thresholds (VIHL = VL − 0.2V = 1.0V, VIHC = VCC − 0.4V = 5.1V) across this extreme voltage span - enabling direct interfacing between ultra-low-power sensors and legacy 5V microcontrollers.
