Product details
Overview
MAX3376EEBL from Maxim Integrated is a unidirectional dual-channel voltage-level translator IC designed for bidirectional signal isolation 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, provides ±15kV HBM ESD protection on VCC-side I/Os, consumes only 130µA typical quiescent current, and features three-state output mode with <1µA supply current - enabling use in portable SPI/MICROWIRE interfaces between 1.8V ASICs and 3.3V microcontrollers.
For engineers reviewing the MAX3376EEBL datasheet, MAX3376EEBL pinout, MAX3376EEBL application, or MAX3376EEBL equivalent, this page delivers verified electrical parameters, package-specific terminal mapping, real-world timing behavior under load, thermal short-circuit response, and validated alternative parts for multivoltage interface design.
Technical Context
The MAX3376EEBL implements unidirectional level translation (VL → VCC or VCC → VL per channel) using MOSFET-based pass-gate architecture without internal direction control logic. Each channel operates independently with rail-to-rail input thresholds (VIHL = VL − 0.2V, VIHC = VCC − 0.4V) and output drive capability up to 20µA source / 1mA sink at defined logic levels.
It integrates speed-up circuitry including one-shot triggered rise-time accelerators on both VL and VCC sides, enabling 16Mbps operation within specific voltage domains (+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 conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 8Mbps guaranteed over full VL/VCC range; up to 16Mbps at +1.8V–+2.5V or +2.5V–+3.3V domains - enables high-speed SPI clocking without external buffers. |
| Supply Range | VL: +1.2V to +5.5V; VCC: +1.65V to +5.5V - supports direct interfacing between 1.2V/1.8V/2.5V/3.3V/5V logic domains. |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in handheld device I/O routing. |
| Quiescent Current | 130µA typical IQVCC + 16µA typical IQVL - extends battery life in always-on portable communication interfaces. |
| Three-State Leakage | <1µA total supply current and <1µA I/O leakage when THREE-STATE = GND - ensures clean bus arbitration in multidrop systems. |
| Propagation Delay | 210ns max (I/O VL → VCC) and 190ns max (I/O VCC → VL) at 8Mbps, CL = 15pF - meets tPHL/tPLH requirements for 5MHz SPI SCLK timing. |
| Rise/Fall Time | 170ns/20ns (tRVCC/tFVCC) and 180ns/30ns (tRVL/tFVL) at 8Mbps - reduces EMI in dense PCB layouts near RF sections. |
Pinout & Package
MAX3376EEBL is packaged in an 8-pin TDFN (3mm × 3mm, 0.5mm pitch) with exposed pad. Pin 1 is marked by dot; EP must be soldered to GND for thermal and ESD performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EP) | Exposed Pad | Thermal and ESD ground path; must be connected to PCB GND plane for rated 15kV protection and thermal derating compliance. |
| 2 | I/O VL1 | Unidirectional data input/output referenced to VL; accepts 1.2V–5.5V logic; drives VCC-side output when enabled. |
| 3 | I/O VL2 | Second independent VL-referenced I/O channel; electrically isolated from I/O VL1 - supports dual-line SPI or separate control/data paths. |
| 4 | VCC | High-side supply input; powers VCC-referenced outputs and internal bias; requires local 1µF decoupling per Maxim recommendation. |
| 5 | GND | Analog/digital reference common; must be low-impedance connection to system ground plane to maintain noise immunity. |
| 6 | THREE-STATE | Active-low enable for high-impedance output mode; referenced to VL logic thresholds; pulls low to disable both channels simultaneously. |
| 7 | I/O VCC1 | VCC-referenced output corresponding to I/O VL1; swings rail-to-rail between 0V and VCC; sinks 1mA or sources 20µA. |
| 8 | I/O VCC2 | VCC-referenced output corresponding to I/O VL2; identical electrical specs to I/O VCC1 - enables matched timing across dual channels. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-channel architecture | Eliminates direction-control pin overhead and simplifies PCB routing for fixed-direction buses like SPI MOSI/MISO. |
| Rise-time accelerator circuitry | Reduces tR/tF by >50% vs. passive translators - achieves 16Mbps at 1.8V/2.5V without external active components. |
| Thermal short-circuit protection | Automatically forces three-state mode at +152°C junction temperature - prevents latch-up and enables self-recovery after fault clearance. |
| ±15kV HBM ESD on VCC I/Os | Meets IEC 61000-4-2 Level 3 system-level ESD immunity without adding discrete protection devices. |
| Three-state output mode | Reduces total supply current to <1µA and isolates I/O lines - essential for shared-bus applications like SD card interfaces. |

FAQ
What is the maximum data rate supported by MAX3376EEBL under typical operating conditions?
MAX3376EEBL guarantees 8Mbps operation across its full specified voltage range (+1.2V ≤ VL ≤ VCC ≤ +5.5V) with CL = 15pF and driver impedance ≤50Ω. At narrower voltage combinations - specifically +1.8V ≤ VL ≤ VCC ≤ +2.5V or +2.5V ≤ VL ≤ VCC ≤ +3.3V - it achieves up to 16Mbps, as confirmed in the Timing Characteristics table of the official datasheet.
Does MAX3376EEBL support bidirectional level translation?
No, MAX3376EEBL is a unidirectional dual-channel level translator. Each channel translates in one fixed direction: either VL → VCC or VCC → VL. Bidirectional operation requires separate devices like MAX3372E or MAX3373E - the MAX3376EEBL datasheet explicitly states it belongs to the unidirectional subgroup (MAX3374E/MAX3375E/MAX3376E/MAX3379E).
How does the THREE-STATE pin function on MAX3376EEBL?
The THREE-STATE pin on MAX3376EEBL is an active-low control input referenced to VL logic thresholds. Pulling it low places both I/O VL and I/O VCC channels into high-impedance state, reducing total supply current to less than 1µA. For normal operation, connect THREE-STATE to VL (logic high); floating or undefined states may cause unpredictable output behavior.
Can MAX3376EEBL operate with VL = 1.2V and VCC = 5.5V simultaneously?
Yes, MAX3376EEBL supports VL as low as +1.2V and VCC as high as +5.5V concurrently, provided VL ≤ (VCC + 0.3V) - which holds true for this combination. The device maintains guaranteed 8Mbps performance and correct logic threshold referencing (VIHL = VL − 0.2V, VIHC = VCC − 0.4V) across this extreme voltage span.
What thermal protection mechanism does MAX3376EEBL implement?
MAX3376EEBL incorporates thermal short-circuit protection that monitors junction temperature. When TJ reaches +152°C, the device automatically enters three-state output mode to halt current flow. Normal operation resumes once TJ cools to +142°C - providing self-recovering fault tolerance without requiring system-level intervention or reset signaling.
