Product details
Overview
MAX3375EEBL+T from Maxim Integrated is a unidirectional, ±15kV ESD-protected voltage-level translator supporting 8Mbps data rate (at +1.2V ≤ VL ≤ VCC ≤ +5.5V), 16Mbps (at +1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V), and 10Mbps (at +1.2V ≤ VL ≤ VCC ≤ +3.3V). It operates with VL as low as +1.2V and VCC as low as +1.65V, enabling interface between low-voltage ASICs/PLDs and higher-voltage systems. Its three-state output mode draws <1µA, and it features thermal short-circuit protection.
For engineers reviewing the MAX3375EEBL+T datasheet, MAX3375EEBL+T pinout, MAX3375EEBL+T application, or MAX3375EEBL+T equivalent, key selection criteria include guaranteed 8Mbps operation across full voltage range, bidirectional vs. unidirectional topology confirmation, VL/VCC supply flexibility (+1.2V to +5.5V), ±15kV HBM ESD rating on VCC-side I/Os, and compatibility with SPI/MICROWIRE/I²C level-shifting requirements in portable and industrial embedded designs.
Technical Context
The MAX3375EEBL+T implements unidirectional level translation (VL → VCC only) using MOSFET-based pass-gate architecture without internal direction control logic. It supports rail-to-rail input/output swing and includes integrated rise-time accelerators for high-speed transitions - reducing tR/tF to 15–40ns under optimal voltage conditions.
Three-state enable is referenced to VL, with logic thresholds VIH = VL − 0.2V and VIL = 0.15V. Thermal shutdown activates at +152°C junction temperature and recovers at +142°C, forcing device into high-impedance state during fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Directionality | Unidirectional (VL → VCC only); no automatic direction sensing or bidirectional capability. |
| Max Data Rate | 8Mbps guaranteed over full VL/VCC operating range (+1.2V to +5.5V); up to 16Mbps within constrained domains (+1.8V–+2.5V or +2.5V–+3.3V). |
| ESD Protection | ±15kV Human Body Model on I/O VCC pins; ±8kV IEC 1000-4-2 contact discharge. |
| Supply Range | VL: +1.2V to +5.5V; VCC: +1.65V to +5.5V; VL must not exceed VCC + 0.3V during operation. |
| Three-State Current | <1µA total supply current (VCC + VL) when THREE-STATE pin pulled low. |
| Propagation Delay | 190–1000ns (I/O VL→VCC or I/O VCC→VL), dependent on load capacitance and voltage domain. |
| Output Drive | Push-pull outputs on both sides; no open-drain configuration required for standard use. |
Pinout & Package
The MAX3375EEBL+T is packaged in a 14-pin TDFN-EP (3mm × 3mm) with exposed pad. Pin functions are defined per the MAX3377E/MAX3378E/MAX3379E quad-level-translator pinout, as confirmed by Maxim's official pin description table and package drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 14) | High-side supply input | Power source for VCC-referenced I/Os; must be ≥ +1.65V and ≤ +5.5V; supplies internal logic and output drivers on VCC side. |
| VL (Pin 7) | Low-side supply input | Reference for VL-referenced I/Os and THREE-STATE logic; sets input thresholds (VIHL = VL − 0.2V) and enables operation down to +1.2V. |
| THREE-STATE (Pin 6) | Enable control input | Pull low to place all I/Os in high-impedance state; referenced to VL; deactivates internal 10kΩ pullups on I/O lines. |
| GND (Pin 10) | Ground reference | Common return path for both supply domains; EP must be soldered to GND for thermal and EMI performance. |
| I/O VL1–VL4 (Pins 1,2,5,6) | Low-voltage data interfaces | Four bidirectional-capable VL-referenced terminals; for MAX3375E, only two channels are active (VL1/VL2), others are NC per ordering guide. |
| I/O VCC1–VCC4 (Pins 13,12,11,8) | High-voltage data interfaces | Four VCC-referenced terminals; MAX3375E uses VCC1/VCC2 only; unused pins are N.C. and must be left floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 8Mbps operation | Enables reliable high-speed serial communication (e.g., SPI at 8MHz clock) across full VL/VCC voltage range without derating. |
| ±15kV HBM ESD on VCC I/Os | Eliminates need for external TVS diodes on VCC-side signal lines in handheld or externally routed applications. |
| Sub-1µA three-state quiescent current | Supports ultra-low-power system sleep modes where level translators remain powered but electrically isolated. |
| Rise-time accelerator circuitry | Reduces tR/tF to ≤15ns in +2.5V/+3.3V domains, minimizing timing skew and enabling clean signal integrity at 16Mbps. |
| Thermal short-circuit protection | Automatically disables outputs at +152°C junction temperature, preventing latch-up or permanent damage during bus contention or wiring faults. |

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; 4-channel; supports 100Mbps; requires external pullup on DIR pin; no thermal protection. | Better for bidirectional buses like I²C; unsuitable where fixed VL→VCC direction and fault resilience are mandatory. | Select MAX3375EEBL+T when deterministic unidirectionality, ±15kV HBM, and thermal shutdown are required. |
| SN74AVCH4T245PW | 4-bit configurable dual-supply translator; 3.6V max VCC; no ESD rating beyond JEDEC standards; 3.3V max VL. | Limited to lower-voltage systems; lacks certified ±15kV protection needed for external connectors. | Choose MAX3375EEBL+T for designs requiring robust ESD immunity on exposed ports or operation below +1.65V VL. |
Compared with TXB0104RUTR and SN74AVCH4T245PW, the MAX3375EEBL+T delivers guaranteed 8Mbps unidirectional translation with industry-leading ±15kV HBM ESD protection and integrated thermal fault response - critical for portable equipment with user-accessible interfaces and extended field reliability requirements.

FAQ
What is the maximum guaranteed data rate for MAX3375EEBL+T across its full operating voltage range?
The MAX3375EEBL+T guarantees 8Mbps operation for +1.2V ≤ VL ≤ VCC ≤ +5.5V, as specified in the Timing Characteristics table. Higher rates - up to 16Mbps - are achievable only within narrower voltage domains: +1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V. The MAX3375EEBL+T does not guarantee 16Mbps across the full range, and design margins must account for load capacitance and driver impedance per Figure 1c/d in the datasheet.
Is MAX3375EEBL+T bidirectional or unidirectional?
The MAX3375EEBL+T is a unidirectional level translator, configured for VL → VCC translation only. It lacks auto-direction sensing or transmission-gate architecture used in MAX3372E/MAX3377E. This is confirmed by its placement in the MAX3374E/MAX3375E/MAX3376E/MAX3379E subgroup and absence of bidirectional timing specifications in its electrical tables.
Does MAX3375EEBL+T require external pull-up resistors on its I/O lines?
No, the MAX3375EEBL+T integrates 10kΩ internal pull-up resistors on both I/O VL and I/O VCC lines during normal operation. These are disconnected automatically when the THREE-STATE pin is pulled low. External pull-ups are unnecessary unless specific bus topology (e.g., wired-OR) demands stronger drive strength or different voltage referencing.
What is the purpose of the exposed pad (EP) on the MAX3375EEBL+T TDFN package?
The exposed pad (EP) on the MAX3375EEBL+T serves dual thermal and electrical functions: it must be soldered to a solid GND plane to enhance heat dissipation (critical for thermal shutdown accuracy) and reduce ground inductance, which improves ESD transient response and signal integrity. Leaving EP unconnected degrades thermal performance and may compromise ±15kV ESD rating compliance.
Can MAX3375EEBL+T operate with VL = +1.2V and VCC = +5.5V simultaneously?
Yes, the MAX3375EEBL+T supports VL as low as +1.2V and VCC as high as +5.5V concurrently, provided VL ≤ VCC + 0.3V (which holds true here). This configuration enables interfacing ultra-low-power sensors (+1.2V IO) with legacy 5V peripherals. However, propagation delay increases to ~1000ns and maximum data rate drops to 8Mbps - verified in the Timing Characteristics table under "+1.2V ≤ VL ≤ VCC ≤ +5.5V" conditions.
