Product details
Overview
MAX3001EEUP+ from Maxim Integrated is an 8-channel bidirectional logic-level translator IC designed for voltage translation between low-voltage (VL = +1.2V to +5.5V) and higher-voltage (VCC = +1.65V to +5.5V) domains. It operates at a guaranteed data rate of 4Mbps, features ±15kV HBM ESD protection on I/O VCC lines, consumes only 0.1µA in shutdown mode, and is housed in a 20-pin TSSOP package. It enables reliable SPI and MICROWIRE interface bridging in portable communication devices.
For engineers reviewing the MAX3001EEUP+ datasheet, MAX3001EEUP+ pinout, MAX3001EEUP+ application, or MAX3001EEUP+ equivalent, key selection criteria include its bidirectional operation without direction control, guaranteed 4Mbps throughput across full VL/VCC ranges, ultra-low shutdown current (<2µA), ±15kV ESD robustness on VCC-side I/Os, and compatibility with 1.2V–5.5V multivoltage system interconnects.
Technical Context
The MAX3001EEUP+ uses a dedicated bidirectional architecture that eliminates the need for a direction-control pin-signals flow automatically from VL ↔ VCC based on active edge detection. Its one-shot accelerator output stage activates only during signal transitions, minimizing quiescent current while enabling fast edge response.
It supports independent supply rails: VL sets the low-voltage domain logic thresholds (VIHL = 2/3×VL, VILL = 1/3×VL), while VCC defines high-side thresholds (VIHC = 2/3×VCC, VILC = 1/3×VCC). EN input controls three-state output mode on all eight VCC-side I/Os, with internal 6kΩ pulldowns active on VL-side I/Os during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Guaranteed 4Mbps - ensures reliable SPI/MICROWIRE timing margins at typical handheld device clock speeds. |
| VL Supply Range | +1.2V to +5.5V - enables direct interfacing with 1.2V ASICs, 1.8V FPGAs, and 3.3V microcontrollers. |
| VCC Supply Range | +1.65V to +5.5V - supports legacy 5V systems and modern low-power 3.3V/2.5V buses. |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in exposed signal paths (e.g., cellphone cradles). |
| Shutdown Current | <2µA total (VCC + VL) - extends battery life in always-on portable POS or GPS receivers. |
| Propagation Delay | 50ns max (I/O VL → I/O VCC) - meets setup/hold timing for 4Mbps SPI with ≤20pF load. |
| Channel Count | 8 independent bidirectional channels - replaces multiple discrete translators in compact space-constrained designs. |
Pinout & Package
MAX3001EEUP+ is packaged in a 20-pin TSSOP (5.0mm × 6.5mm, 0.65mm pitch) with exposed pad (EP) connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3–9 (I/O VL1–I/O VL8) | Bidirectional I/O referenced to VL | Connect to low-voltage side signals (e.g., 1.8V FPGA I/O); auto-sense direction per channel. |
| 10 (EN) | Enable input | Pull low to place all I/O VCCx in high-impedance state; internal 6kΩ pulldowns engage on I/O VLx. |
| 11 (GND) | Ground reference | Common return for both VL and VCC supplies; must be low-inductance connection to EP. |
| 12–20 (I/O VCC8–I/O VCC1) | Bidirectional I/O referenced to VCC | Interface to higher-voltage domain (e.g., 3.3V MCU SPI bus); level-shifted output matches VCC logic levels. |
| 19 (VCC) | High-side supply | +1.65V to +5.5V rail; bypass with 0.1µF ceramic capacitor close to pin. |
| 2 (VL) | Low-side supply | +1.2V to +5.5V rail; bypass with 0.1µF ceramic capacitor close to pin; must be ≤ VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation | No direction pin required - reduces PCB routing complexity and firmware overhead in full-duplex interfaces like SPI. |
| ±15kV HBM ESD on VCC I/Os | Eliminates external protection components in consumer-facing ports (e.g., USB-to-SPI adapters, smart card readers). |
| 0.1µA shutdown supply current | Enables true "off" state in battery-powered applications without sacrificing wake-up latency. |
| 1.2V minimum VL operation | Supports next-generation ultra-low-voltage SoCs and energy-harvesting sensor nodes. |
| 8-channel integration | Replaces up to eight discrete MOSFET-based translators, saving >30mm² board area in TSSOP footprint. |

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; no ±15kV ESD rating; 100Mbps max but only at 3.3V/1.8V. | Best suited for high-speed, direction-stable buses (e.g., parallel memory); not ideal for hot-plug SPI or exposed I/O. | Select when speed >4Mbps is mandatory and ESD exposure is controlled; avoid for cradle/smart card use. |
| SN74AVC8T245RHLR | Direction-controlled; 3.6V max VCC; no guaranteed 1.2V VL operation; 12mA drive strength vs. MAX3001E's passive translation. | Preferred for industrial backplanes with fixed direction and higher drive needs; lacks ESD hardening for consumer ports. | Choose for 3.3V↔5V translation where ±15kV ESD is unnecessary and layout allows direction signal routing. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, the MAX3001EEUP+ delivers verified bidirectional operation without control logic overhead, industry-leading ±15kV ESD protection on exposed I/Os, and guaranteed 4Mbps performance down to 1.2V VL-making it uniquely suitable for portable, user-accessible interfaces.

FAQ
What is the maximum guaranteed data rate for MAX3001EEUP+?
The MAX3001EEUP+ is guaranteed to operate at 4Mbps across its full 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 specification is validated under standard test conditions (RS = 50Ω, CVCC = 50pF) and applies to bidirectional signal translation in both directions (VL ↔ VCC).
Does MAX3001EEUP+ require a direction-control pin?
No, the MAX3001EEUP+ does not require a direction-control pin. It uses a proprietary bidirectional architecture that automatically detects signal edges on either side (VL or VCC) and translates accordingly. This eliminates firmware overhead and PCB routing for direction signals-unlike unidirectional translators such as SN74AVC8T245RHLR.
What is the ESD protection rating for MAX3001EEUP+?
The MAX3001EEUP+ provides ±15kV Human Body Model (HBM) ESD protection specifically on all I/O VCC pins. This rating is confirmed per JEDEC JS-001 and applies during normal operation, three-state mode, and shutdown-ensuring reliability in user-accessible interfaces like cellphone cradles and smart card slots without external protection components.
Can MAX3001EEUP+ operate with VL higher than VCC?
No-VL must be ≤ VCC for proper operation. However, the MAX3001EEUP+ is designed to tolerate VL ≥ VCC during power-up sequencing without damage. The device remains functional and latch-up free even if VL powers up before VCC, making it robust in systems with asynchronous supply ramping.
What package type is used for MAX3001EEUP+?
The MAX3001EEUP+ is supplied in a 20-pin TSSOP (Thin Shrink Small Outline Package) with dimensions 6.5mm × 5.0mm and 0.65mm lead pitch. It includes an exposed thermal pad (EP) that must be soldered to a GND plane for optimal thermal performance and EMI suppression.
