Product details
Overview
MAX3000EEUP+T from Maxim Integrated is an 8-channel bidirectional logic-level translator IC designed for voltage-domain bridging between low-voltage (VL = +1.2V to +5.5V) and higher-voltage (VCC = +1.65V to +5.5V) digital systems. It operates without a direction control pin, delivers guaranteed 230kbps data rate, features ±15kV HBM ESD protection on I/O VCC lines, and supports TSSOP-20 packaging for space-constrained portable electronics such as smart card readers and cellphone cradles.
For engineers reviewing the MAX3000EEUP+T datasheet, MAX3000EEUP+T pinout, MAX3000EEUP+T application, or MAX3000EEUP+T equivalent, this page provides verified electrical specifications, bidirectional timing behavior, EN-controlled shutdown mode, real-world load-capacitance dependencies, and validated alternative parts for multivoltage interface design in industrial and consumer embedded systems.
Technical Context
The MAX3000EEUP+T implements a passive-bidirectional architecture with no direction pin-signal flow occurs automatically VL ↔ VCC based on transient edge detection at either side. Its internal accelerator output stage activates only during signal transitions, minimizing quiescent current while enabling rail-to-rail level shifting across the full VL/VCC operating range.
It uses dual-supply referenced I/O banks: eight I/O VL pins (1–8) referenced to VL, eight I/O VCC pins (1–8) referenced to VCC, plus dedicated EN, GND, VL, and VCC terminals. The EN input places all I/O VCC pins in high-impedance state while applying 6kΩ pulldowns to I/O VL pins, reducing total supply current to <2µA in shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Guaranteed 230kbps-supports reliable SPI/MICROWIRE translation in low-speed sensor interfaces and legacy serial buses. |
| VL Supply Range | +1.2V to +5.5V-enables direct interfacing with 1.2V/1.8V/2.5V/3.3V ASICs, PLDs, and microcontrollers. |
| VCC Supply Range | +1.65V to +5.5V-compatible with 1.8V/2.5V/3.3V/5V host systems and peripheral controllers. |
| ESD Protection | ±15kV HBM on I/O VCC pins-eliminates need for external TVS diodes in handheld device I/O routing. |
| Shutdown Current | <2µA total (VCC + VL)-enables battery-powered operation with extended sleep duration in portable POS and GPS modules. |
| Propagation Delay | 1000ns max (I/O VL → I/O VCC), 1000ns max (I/O VCC → I/O VL)-predictable latency for deterministic timing in synchronous protocols. |
| Channel Count | 8 independent bidirectional channels-replaces multiple discrete translators in compact multibus designs. |
Pinout & Package
MAX3000EEUP+T is housed in a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed pad for thermal management. Pin 1 is I/O VL1; pin 10 is EN; pin 11 is GND; pin 19 is VCC; pin 20 is I/O VCC1. All VL and VCC supplies require local 0.1µF bypass capacitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–I/O VL8 | Bidirectional I/O bank referenced to VL | Accepts or drives signals at VL logic levels; auto-senses direction per channel during transitions. |
| I/O VCC1–I/O VCC8 | Bidirectional I/O bank referenced to VCC | Translates VL-side signals to VCC logic levels and vice versa; no external direction control needed. |
| VL | Low-voltage supply reference | Defines logic thresholds (VIHL = 2/3×VL, VILL = 1/3×VL); must be ≤ VCC and ≥ +1.2V. |
| VCC | High-voltage supply reference | Sets VCC-side thresholds (VIHC = 2/3×VCC, VILC = 1/3×VCC); minimum +1.65V required. |
| EN | Enable control input | Pull low to place I/O VCC pins in three-state and activate 6kΩ pulldowns on I/O VL pins. |
| GND | Common ground reference | Return path for both VL and VCC supplies; connects to exposed pad for thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation without direction pin | Enables seamless VL ↔ VCC data flow on each of 8 channels-no firmware overhead or PCB routing for DIR signals. |
| ±15kV HBM ESD protection on I/O VCC | Meets IEC 61000-4-2 Level 4 for system-level robustness-no external protection components required on VCC-side I/O traces. |
| Ultra-low shutdown current (<2µA) | Extends battery life in always-on portable devices; enables fast wake-up (<2µs) via EN assertion without reset sequence. |
| 1.2V minimum VL operation | Supports next-generation ultra-low-power processors and memory interfaces operating at 1.2V core voltage. |
| Guaranteed 230kbps over full voltage range | Ensures interoperability across VL = 1.2V–5.5V and VCC = 1.65V–5.5V combinations without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108PWR | Unidirectional architecture; requires separate TX/RX pairs per channel; no built-in ESD protection. | Requires external ±15kV TVS diodes on all VCC-side I/O; not suitable for hot-plug or field-serviceable interfaces. | Select when cost sensitivity outweighs ESD robustness and board space is available for discrete protection. |
| SN74AVC8T245RHLR | Direction-controlled (DIR pin required); 3.6V max VCC; no 1.2V VL support; lower ESD rating (±8kV). | Limited to 1.5V–3.6V domain translation; unsuitable for 1.2V ASIC interfacing or industrial environments with high ESD stress. | Choose only for legacy 1.5V/1.8V/2.5V/3.3V systems where DIR pin routing is acceptable and ESD exposure is controlled. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, MAX3000EEUP+T uniquely combines true bidirectionality without direction control, 1.2V VL compatibility, ±15kV HBM ESD on VCC I/O, and guaranteed 230kbps performance across its full voltage range-making it optimal for compact, field-deployed, and battery-operated multivoltage interfaces.

FAQ
What is the maximum guaranteed data rate for MAX3000EEUP+T?
The MAX3000EEUP+T guarantees a data rate of 230kbps across its entire specified operating voltage range (VL = +1.2V to +5.5V, VCC = +1.65V to +5.5V) and temperature range (-40°C to +85°C). This value is production-tested and does not require derating for typical load conditions up to 50pF.
Does MAX3000EEUP+T require a direction control signal?
No, MAX3000EEUP+T uses a passive-bidirectional architecture that automatically detects signal direction per channel based on edge transitions-no DIR pin or firmware configuration is needed. This simplifies PCB layout and eliminates timing-critical direction-control sequencing.
What is the purpose of the EN pin on MAX3000EEUP+T?
The EN pin on MAX3000EEUP+T controls shutdown mode: pulling EN low places all I/O VCC pins in high-impedance state and activates 6kΩ pulldown resistors on all I/O VL pins, reducing total supply current to less than 2µA. Driving EN high (to VL) enables normal bidirectional operation.
Can MAX3000EEUP+T operate with VL greater than VCC?
During power-up sequencing, VL may exceed VCC without damaging MAX3000EEUP+T-this is explicitly permitted per the Absolute Maximum Ratings table. However, for stable functional operation, VL must be ≤ VCC per the Electrical Characteristics section; sustained VL > VCC violates specification limits.
Is external ESD protection required for MAX3000EEUP+T?
No external ESD protection is required on the I/O VCC pins of MAX3000EEUP+T, as it integrates ±15kV Human Body Model (HBM) ESD protection-verified per JEDEC JS-001. External protection remains optional for I/O VL pins, which are rated to standard industry levels.
