Product details
Overview
MAX3001EAUP+T from Maxim Integrated is an 8-channel bidirectional logic-level translator IC enabling voltage translation between +1.2V and +5.5V domains without direction control pins. It supports guaranteed 4Mbps data rate, ±15kV HBM ESD protection on I/O VCC lines, ultra-low 0.1µA shutdown current, and operates across –40°C to +125°C. It is used in SPI/MICROWIRE interfaces between low-voltage ASICs and 3.3V/5V systems.
For engineers reviewing the MAX3001EAUP+T datasheet, MAX3001EAUP+T pinout, MAX3001EAUP+T application, or MAX3001EAUP+T equivalent, key selection criteria include bidirectional operation without direction pin, 4Mbps timing performance at 1.8V/3.3V, EN-controlled three-state outputs, and compatibility with portable communication and smart card reader designs requiring robust ESD immunity.
Technical Context
The MAX3001EAUP+T uses a passive-bidirectional architecture that automatically senses signal transitions on either VL- or VCC-referenced I/Os, eliminating need for external direction control. Its internal accelerator output stage activates only during edge transitions to minimize quiescent current while achieving fast rise/fall times (≤50ns typical at 4Mbps).
It accepts VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, with guaranteed operation when VL ≤ VCC. The EN input places all eight VCC-side I/Os in high-impedance state while enabling 6kΩ pulldowns on VL-side I/Os - critical for bus arbitration and power-gated system states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Guaranteed 4Mbps - enables reliable SPI clocking up to 2MHz with margin for trace capacitance and noise. |
| Supply Range (VL) | +1.2V to +5.5V - supports direct interfacing with 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic domains. |
| Supply Range (VCC) | +1.65V to +5.5V - ensures compatibility with standard microcontroller I/O rails and avoids under-voltage lockout. |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in handheld device USB/UART interfaces. |
| Shutdown Current | 0.1µA max from both VL and VCC - extends battery life in always-on sensor nodes and cradle detection circuits. |
| Propagation Delay | 50ns max (I/O VL → I/O VCC) - meets setup/hold timing for 4Mbps SPI with 20pF load and 50Ω source impedance. |
| Channel Count | 8 independent bidirectional channels - replaces discrete MOSFET translators or multiple 2-channel ICs in compact layouts. |
Pinout & Package
MAX3001EAUP+T is housed in a 20-pin TSSOP package (4.4mm × 6.5mm, 0.65mm pitch) with exposed pad for thermal and ground integrity. Pin numbering follows standard TSSOP convention; EP must be soldered to PCB ground plane.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1,3–9 | I/O VL1–VL8 | Bidirectional data lines referenced to VL supply - connect to low-voltage controller (e.g., 1.8V FPGA I/O bank). |
| 2 | VL | Logic-side supply input - bypass with 0.1µF ceramic capacitor close to pin to suppress switching noise. |
| 10 | EN | Active-high enable - drives high (VL) for normal operation; pulls low to tri-state all I/O VCC lines and activate VL-side pulldowns. |
| 11 | GND | Analog/digital ground reference - tie directly to PCB ground plane; connect EP to same node. |
| 12–18,20 | I/O VCC1–VCC8 | Bidirectional data lines referenced to VCC supply - interface with 3.3V microcontroller peripherals or legacy 5V logic. |
| 19 | VCC | Core-side supply input - bypass with 0.1µF ceramic capacitor; supports 1.65V–5.5V for mixed-voltage system flexibility. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation | No direction pin required - automatic level shifting in both VL ↔ VCC directions per channel, reducing PCB routing complexity. |
| ±15kV ESD protection | On all I/O VCC pins - withstands repeated human-body-model discharges without latch-up or parameter shift, validated per JEDEC JS-001. |
| Ultra-low shutdown current | 0.1µA total supply current - enables use in battery-backed real-time clock domains or wake-on-serial applications. |
| Wide VL operating range | Down to +1.2V - supports next-generation ultra-low-power processors and memory interfaces not feasible with older translators. |
| Thermal-enhanced TSSOP | Exposed pad (EP) connected to GND - improves thermal resistance by ~30°C/W vs. standard TSSOP, enabling sustained 4Mbps operation at +85°C ambient. |

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 per channel; requires direction control signals; lower ESD rating (±8kV); 100Mbps max but only at 3.3V/1.8V. | Not suitable for true bidirectional buses like I²C or half-duplex SPI without external logic. | Select only if direction is fixed per channel and ESD requirements are less stringent. |
| SN74AVC8T245RHLR | Direction-controlled; higher drive strength (24mA); no integrated ESD beyond standard HBM; 3.6V max VCC. | Requires PCB-level direction signal routing and external ESD protection for industrial environments. | Prefer when driving heavy capacitive loads (>30pF) or interfacing with 5V-tolerant 3.3V logic. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, MAX3001EAUP+T uniquely delivers pin-compatible bidirectionality, industry-leading ±15kV ESD immunity, and guaranteed 4Mbps operation down to 1.2V VL - making it optimal for space-constrained, ESD-prone portable designs where direction control overhead is unacceptable.

FAQ
What is the maximum guaranteed data rate for MAX3001EAUP+T?
The MAX3001EAUP+T is guaranteed to operate at 4Mbps across its full specified voltage and temperature range (–40°C to +125°C), with typical rise/fall times of 25ns–50ns under 50pF load conditions. This rate is validated for bidirectional SPI and MICROWIRE interfaces with 1.8V/3.3V domain translation.
Does MAX3001EAUP+T require a direction control signal?
No, MAX3001EAUP+T does not require a direction control signal. Its architecture enables automatic bidirectional level translation on each of its eight channels, allowing simultaneous or alternating signal flow between VL and VCC domains without external logic or timing constraints.
What is the purpose of the EN pin on MAX3001EAUP+T?
The EN pin on MAX3001EAUP+T controls output enable state: when pulled low, all eight I/O VCC lines enter high-impedance three-state mode while internal 6kΩ pulldown resistors activate on I/O VL lines. This supports bus sharing, low-power sleep modes, and safe hot-plug scenarios in the MAX3001EAUP+T design.
Can MAX3001EAUP+T translate between 1.2V and 5V logic levels?
Yes, MAX3001EAUP+T supports VL from +1.2V to +5.5V and VCC from +1.65V to +5.5V, with guaranteed operation when VL ≤ VCC. Translation between 1.2V (VL) and 5V (VCC) is supported, though timing margins tighten at extreme ratios - verify propagation delay and noise margin for specific 1.2V→5V use cases in the MAX3001EAUP+T datasheet.
Is MAX3001EAUP+T compatible with I²C bus protocols?
MAX3001EAUP+T is not recommended for standard I²C due to lack of open-drain emulation and weak pull-up capability on VL side. Its bidirectional architecture assumes push-pull drivers; for I²C, dedicated translators like MAX3372E or PCA9306 are preferred. MAX3001EAUP+T excels in SPI, UART, and GPIO translation instead.
