Product details
Overview
MAX3001EEUP+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 guarantees 4Mbps data rate, supports ±15kV HBM ESD protection on I/O VCC lines, operates from -40°C to +85°C, and features ultra-low 0.1µA shutdown current. It is used in SPI/MICROWIRE interfaces between low-voltage ASICs and 3.3V/5V systems.
For engineers reviewing the MAX3001EEUP+T datasheet, MAX3001EEUP+T pinout, MAX3001EEUP+T application, or MAX3001EEUP+T equivalent, this page delivers verified electrical specs, TSSOP-20 pin mapping, real-world use cases in portable comms and smart card readers, and two validated alternative parts with functional and packaging distinctions.
Technical Context
The MAX3001EEUP+T implements a passive-bidirectional architecture that eliminates the need for external direction control signals - signal flow is automatically determined by the active driver side (VL ↔ VCC). Its internal accelerator output stage activates only during signal transitions, minimizing quiescent current while achieving fast edge rates.
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 enables three-state mode on all eight VCC-side I/Os while applying 6kΩ pulldowns to VL-side I/Os, supporting bus isolation in multi-drop systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Guaranteed 4Mbps - supports high-speed SPI clocking up to ~2MHz SCLK with margin. |
| Supply Voltage Range | VL: +1.2V to +5.5V; VCC: +1.65V to +5.5V - enables interfacing between 1.2V/1.8V logic and 3.3V/5V peripherals. |
| ESD Protection | ±15kV HBM on I/O VCC pins - protects against handling damage in exposed signal routing (e.g., cellphone cradles). |
| Shutdown Current | <0.1µA total (VCC + VL) - enables battery-powered sleep modes in portable POS and GPS devices. |
| Propagation Delay | 50ns max (I/O VL → I/O VCC), 65ns max (I/O VCC → I/O VL) at 4Mbps - ensures timing compliance in 20MHz SPI read/write cycles. |
| Channel Count | 8 independent bidirectional channels - replaces discrete MOSFET translators for compact 8-bit data buses. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and automotive accessory environments. |
Pinout & Package
MAX3001EEUP+T is housed in a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is I/O VL1; pin 19 is VCC; pin 11 is GND; pin 10 is EN; pin 20 is I/O VCC1. All I/O VL pins (1,3–9) reference VL; all I/O VCC pins (12–18,20) reference VCC.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1,3–9 | I/O VLn | Bidirectional data channel referenced to VL supply - connects to 1.2V–5.5V low-voltage side (e.g., FPGA I/O bank). |
| 2 | VL | Logic-reference supply input - must be bypassed with 0.1µF capacitor to GND; sets low-voltage domain threshold. |
| 10 | EN | Enable input - pulled low disables all I/O VCC outputs (three-state) and activates 6kΩ pulldowns on I/O VL lines. |
| 11 | GND | Common ground reference - connects to both VL and VCC return paths; exposed pad must be soldered to GND plane. |
| 12–18,20 | I/O VCCn | Bidirectional data channel referenced to VCC supply - connects to 1.65V–5.5V higher-voltage side (e.g., microcontroller GPIO). |
| 19 | VCC | High-side supply input - must be bypassed with 0.1µF capacitor to GND; defines high-voltage logic thresholds (VIHC/VILC = 2/3 & 1/3 × VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation without direction pin | Enables automatic signal flow detection - eliminates PCB routing for DIR lines and firmware overhead in SPI/MICROWIRE bridges. |

| 0.1µA shutdown supply current | Reduces system standby power by >99% vs. active mode - extends battery life in portable GPS and smart card readers. |
| 1.2V minimum VL operation | Supports next-generation ultra-low-power ASICs and PLDs - maintains full functionality down to 1.2V core logic. |
| 8-channel integration in TSSOP-20 | Replaces eight discrete level-shifter solutions - saves >70% board area vs. dual-SOT23 implementations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108PWR | 8-channel auto-directional translator; 3.6V max VCC; no ±15kV ESD; 100Mbps rated but requires ≥1.65V VL. | Lacks ESD hardening for exposed interfaces; better suited for internal board-level translation only. | Select when higher speed (100Mbps) is required and ESD exposure is controlled; verify VL ≥1.65V compatibility. |
| SN74AVC8T245RHLR | 8-bit unidirectional translator with direction pin; 3.6V max; 24mA drive; no integrated ESD beyond standard HBM. | Requires external direction control and pull-ups; not suitable for true bidirectional protocols like SPI full-duplex. | Choose only for fixed-direction data paths (e.g., parallel address/data buses); avoid for SPI/MICROWIRE where bidirectionality is essential. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, MAX3001EEUP+T uniquely combines guaranteed 4Mbps bidirectional operation, ±15kV I/O VCC ESD protection, and 1.2V VL support - making it the only option qualified for ruggedized portable communication interfaces requiring zero-direction-pin simplicity and field-reliable ESD immunity.

FAQ
What is the maximum guaranteed data rate for MAX3001EEUP+T?
The MAX3001EEUP+T guarantees 4Mbps operation across its full operating voltage range (+1.2V VL to +5.5V VCC) and temperature range (-40°C to +85°C). This is confirmed in the Timing Characteristics table under "Maximum Data Rate" for MAX3001E, with typical rise/fall times of 25–50ns and propagation delays ≤65ns at 4Mbps loading conditions.
Does MAX3001EEUP+T support true bidirectional operation without a direction control pin?
Yes, MAX3001EEUP+T uses a proprietary passive-bidirectional architecture that detects signal activity on either side (VL or VCC) and automatically routes translation accordingly. No external DIR pin is needed - unlike unidirectional translators such as SN74AVC8T245RHLR. This is explicitly stated in the General Description and Detailed Description sections of the datasheet.
What is the ESD protection rating on MAX3001EEUP+T I/O pins?
The MAX3001EEUP+T provides ±15kV Human Body Model (HBM) ESD protection specifically on all I/O VCC pins (pins 12–18,20), as documented in the ESD PROTECTION section. This exceeds JEDEC standards and is validated for reliability across all operational states - including shutdown and three-state modes.
Can MAX3001EEUP+T operate with VL = 1.2V and VCC = 3.3V simultaneously?
Yes, MAX3001EEUP+T is fully specified for VL = +1.2V to +5.5V and VCC = +1.65V to +5.5V, with VL ≤ VCC. Operation at VL = 1.2V and VCC = 3.3V is explicitly supported and tested - enabling interface between 1.2V ASICs and standard 3.3V peripherals, as confirmed in the Electrical Characteristics and Applications sections.
What happens to the I/O pins when EN is pulled low on MAX3001EEUP+T?
When EN is pulled low, all eight I/O VCC pins (12–18,20) enter high-impedance three-state mode, while all eight I/O VL pins (1,3–9) are actively pulled down via internal 6kΩ resistors to VL. This behavior is defined in the Pin Description and Detailed Description sections and enables safe bus sharing and power-gated isolation in multi-peripheral systems.
