Product details
Overview
The MAX3374EEBL-T from Maxim Integrated is a unidirectional, ±15kV ESD-protected voltage-level translator designed for bidirectional signal routing between low-voltage (VL = +1.2V to +5.5V) and higher-voltage (VCC = +1.65V to +5.5V) domains. It supports guaranteed 8Mbps data rate across full voltage range, features ultra-low 1µA three-state supply current, and operates in 14-pin TDFN (3mm × 3mm) package. It enables reliable SPI and I²C level translation in portable communication devices.
For engineers reviewing the MAX3374EEBL-T datasheet, MAX3374EEBL-T pinout, MAX3374EEBL-T application, or MAX3374EEBL-T equivalent, key selection criteria include its unidirectional VL→VCC/VCC→VL translation capability, 8Mbps guaranteed timing over +1.2V ≤ VL ≤ VCC ≤ +5.5V, ±15kV HBM ESD rating on VCC-side I/Os, thermal short-circuit protection, and support for three-state output mode with sub-1µA quiescent current.
Technical Context
The MAX3374EEBL-T implements unidirectional level shifting using MOSFET-based pass-gate architecture without internal direction control logic-data flow direction is fixed per channel by external connection. It requires separate VL and VCC supplies, with logic thresholds referenced to respective rails: VIHL = VL − 0.2V, VILC = 0.15V, VOHC = 0.67×VCC, VOLC = 0.4V (sink = 1mA).
Its speed-up circuitry includes edge-triggered rise-time accelerators on both VL and VCC sides, enabling 16Mbps operation under specific voltage conditions (+1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V). Thermal shutdown activates at TJ = +152°C and recovers at +142°C, forcing three-state mode during fault.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E | 4-channel auto-direction sensing; no THREE-STATE pin; max 60Mbps; VL/VCC = 1.2V–3.6V only | Requires no direction-control signal but lacks thermal shutdown and ±15kV HBM rating | Select when automatic bidirectional detection is needed and ESD requirements are ≤±8kV |
| SN74AVC4T245 | 4-bit bus transceiver with direction control (DIR); 3.6V max VCC; no integrated ESD protection beyond standard HBM | Requires external ±15kV TVS diodes on I/Os; higher quiescent current (~10µA in 3-state) | Select when board space allows discrete ESD protection and DIR-controlled operation is preferred |
Compared with TXS0104E and SN74AVC4T245, the MAX3374EEBL-T provides superior ESD robustness (±15kV HBM), integrated thermal protection, and guaranteed 8Mbps performance across wider voltage ranges (+1.2V to +5.5V VL, +1.65V to +5.5V VCC), making it optimal for ruggedized portable interfaces where reliability trumps raw speed.

FAQ
What is the maximum guaranteed data rate for MAX3374EEBL-T across its full operating voltage range?
The MAX3374EEBL-T guarantees 8Mbps operation for all combinations where +1.2V ≤ VL ≤ VCC ≤ +5.5V and load capacitance ≤15pF. Higher rates up to 16Mbps are achievable within narrower voltage windows: +1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V, as confirmed in the Timing Characteristics table.
Does MAX3374EEBL-T support bidirectional level translation on a single pin pair?
No - the MAX3374EEBL-T is a unidirectional level translator. Each I/O VLx/I/O VCCx pair is configured for fixed direction: either VL→VCC or VCC→VL, determined by external wiring. Bidirectional operation requires MAX3372E/MAX3373E or MAX3377E/MAX3378E variants with transmission-gate architecture.
How does the THREE-STATE pin function on MAX3374EEBL-T, and what is its voltage reference?
The THREE-STATE pin on MAX3374EEBL-T is referenced to VL. Pulling it low (≤0.15V) places all I/O VLx and I/O VCCx pins in high-impedance state and reduces total supply current to <1µA. For normal operation, connect THREE-STATE to VL (logic-high). Do not exceed (VL + 0.3V) on this pin.
Can MAX3374EEBL-T be used with VL = +1.2V and VCC = +5.5V simultaneously?
Yes - the MAX3374EEBL-T explicitly supports VL as low as +1.2V and VCC as high as +5.5V, provided VL ≤ (VCC + 0.3V), which holds true here. Electrical characteristics including VOHL = 0.67×VL and VOHC = 0.67×VCC remain valid, ensuring correct logic-level interpretation across the full range.
What thermal protection mechanism does MAX3374EEBL-T implement, and how does it recover?
The MAX3374EEBL-T integrates thermal short-circuit protection that monitors junction temperature. At TJ = +152°C, it automatically forces the device into three-state output mode. Recovery occurs autonomously when TJ cools to +142°C, restoring normal operation without requiring power cycle or external intervention - a key reliability feature for unattended portable systems.
