Product details
Overview
MAX3377EEBC from Maxim Integrated is a quad bidirectional voltage-level translator IC enabling seamless data exchange between +1.2V to +5.5V logic domains (VL) and +1.65V to +5.5V systems (VCC), with guaranteed 230kbps operation, ±15kV HBM ESD protection on VCC-side I/Os, and ultra-low 1µA three-state supply current - deployed in portable POS systems and smart card readers.
For engineers reviewing the MAX3377EEBC datasheet, MAX3377EEBC pinout, MAX3377EEBC application, or MAX3377EEBC equivalent, this page delivers verified electrical specs, bidirectional timing behavior under VL/VCC voltage constraints, thermal short-circuit protection details, and real-world interface compatibility for SPI/MICROWIRE/I²C multivoltage interconnects.
Technical Context
The MAX3377EEBC uses a transmission-gate-based architecture to support true bidirectional level translation (VL ↔ VCC) across all four channels without direction control pins. It operates with independent VL and VCC supplies, where VL accepts +1.2V to +5.5V and VCC supports +1.65V to +5.5V - with VL ≤ (VCC + 0.3V) required for safe operation.
It features slew-rate limiting to reduce EMI emissions, thermal shutdown activation at +152°C junction temperature, and three-state output mode activated by pulling the THREE-STATE pin low - placing all I/Os in high-impedance state while drawing <1µA total supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Direction | Bidirectional (VL ↔ VCC) - no direction control needed per channel; enables shared bus arbitration in mixed-voltage I²C/SPI systems. |
| Guaranteed Data Rate | 230kbps - specified over full VL (+1.2V to +5.5V) and VCC (+1.65V to +5.5V) range; supports reliable low-speed sensor/EEPROM interfacing. |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in handheld device I/O routing. |
| Three-State Supply Current | <1µA - enables power gating in battery-powered devices during idle or sleep modes without signal leakage. |
| Supply Voltage Range | VL: +1.2V to +5.5V; VCC: +1.65V to +5.5V - allows interfacing legacy 5V microcontrollers with modern 1.2V/1.8V ASICs or FPGAs. |
| Propagation Delay | 1.6µs max (I/O VL ↔ VCC) - ensures deterministic timing for synchronous protocols like SPI clocked below 200kHz. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
Pinout & Package
MAX3377EEBC is packaged in a 14-pin TDFN (3mm × 3mm) with exposed pad. Pin functions are referenced to VL or VCC as indicated; N.C. pins are not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 14) | High-side supply input | Accepts +1.65V to +5.5V; powers VCC-referenced I/Os (I/O VCC1–I/O VCC4) and internal bias circuitry. |
| VL (Pin 2) | Low-side supply input | Accepts +1.2V to +5.5V; sets logic thresholds and powers VL-referenced I/Os (I/O VL1–I/O VL4). |
| THREE-STATE (Pin 3) | Output enable control | Pull low to place all eight I/Os (four VL-side, four VCC-side) in high-impedance state; logic-referenced to VL. |
| GND (Pin 7) | Common reference | System ground return for both supply domains; exposed pad must be soldered to PCB ground plane. |
| I/O VL1–I/O VL4 (Pins 1, 4, 5, 6) | Bidirectional low-voltage data terminals | Each connects to VL-domain signals (e.g., 1.8V I²C lines); automatically adapts direction based on driving side. |
| I/O VCC1–I/O VCC4 (Pins 13, 12, 11, 10) | Bidirectional high-voltage data terminals | Each connects to VCC-domain signals (e.g., 3.3V MCU GPIO); translates voltage levels without external resistors. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E | 8Mbps guaranteed rate; no built-in ESD protection - requires external ±15kV TVS diodes on VCC I/Os. | Higher-speed SPI interfaces (>500kbps); unsuitable for unshielded external I/O routing without added protection. | Select when speed >230kbps is mandatory and board space allows discrete ESD components. |
| SN74AVC4T245 | 3.6V max VCC; no HBM ESD rating beyond JEDEC standard (±2kV); higher quiescent current (10µA three-state). | Internal backplane interconnects only; not recommended for handheld or connector-facing applications. | Choose for cost-sensitive, non-portable systems where ESD exposure is controlled and speed up to 400Mbps is needed. |
Compared with TXS0104E and SN74AVC4T245, MAX3377EEBC uniquely combines guaranteed 230kbps bidirectional operation, integrated ±15kV HBM ESD on VCC I/Os, and sub-1µA three-state current - making it optimal for space-constrained, externally exposed portable interfaces where reliability and low-power sleep matter most.

FAQ
What is the maximum capacitive load the MAX3377EEBC can drive at 230kbps?
The MAX3377EEBC maintains guaranteed 230kbps operation with up to 50pF load capacitance per channel, as validated in the Timing Characteristics table. Driving higher loads (e.g., >100pF) increases propagation delay and rise/fall times - potentially violating setup/hold margins in synchronous protocols. For loads exceeding 50pF, verify timing margins using the Typical Operating Characteristics graphs (e.g., toc10–toc12) with actual VCC/VL conditions. The MAX3377EEBC itself does not specify derating curves beyond 50pF at 230kbps.
Can the MAX3377EEBC translate between 1.2V and 5V logic without external components?
Yes - the MAX3377EEBC supports VL = +1.2V and VCC = +5.0V simultaneously, provided VL ≤ (VCC + 0.3V) is satisfied (1.2V ≤ 5.3V, which holds). No external pull-up resistors, direction-control logic, or level-shifting MOSFETs are required. Its transmission-gate architecture and rail-to-rail output swing (VOHL = 0.67×VL, VOHC = 0.67×VCC) ensure valid logic levels on both sides. However, ensure I/O VCC pins are protected with a 1µF decoupling capacitor to GND for full ±15kV ESD performance.
Does the MAX3377EEBC support open-drain bus protocols like I²C?
Yes - the MAX3377EEBC is explicitly designed for I²C, SPI, and MICROWIRE level translation. Its bidirectional channels operate correctly with open-drain topologies: when an I²C master pulls SDA low on the VL side, the MAX3377EEBC actively drives I/O VCC low; when the master releases SDA, the internal 10kΩ pull-up (enabled in normal mode) on the VCC side restores high state. This preserves I²C's wired-AND behavior without external components.
How does the three-state mode affect I/O voltage limits on the MAX3377EEBC?
When THREE-STATE is pulled low, all I/O VL_ and I/O VCC_ pins enter high-impedance state, but absolute voltage limits remain active: I/O VL_ must not exceed (VL + 0.3V), and I/O VCC_ must not exceed (VCC + 0.3V). Exceeding these violates Absolute Maximum Ratings and risks damage. The MAX3377EEBC does not disable ESD clamps in three-state mode - ±15kV HBM protection remains fully functional on VCC-side I/Os even during sleep.
Is thermal shutdown reversible on the MAX3377EEBC?
Yes - thermal shutdown is fully automatic and reversible. When junction temperature reaches +152°C, the MAX3377EEBC forces itself into three-state mode to reduce power dissipation. Once the die cools to +142°C, normal bidirectional operation resumes without requiring power cycle or reset. This hysteresis prevents oscillation near the trip point and ensures robust fault recovery in thermally constrained enclosures like handheld devices.
