Product details
Overview
MAX3001EEUP 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, draws only 0.1µA supply current in shutdown, and operates across –40°C to +85°C. It is used in SPI/MICROWIRE interfaces between low-voltage ASICs and 3.3V/5V systems.
For engineers reviewing the MAX3001EEUP datasheet, MAX3001EEUP pinout, MAX3001EEUP application, or MAX3001EEUP equivalent, this page delivers verified electrical specs, TSSOP-20 pin mapping, real-world use cases in portable communication devices and smart card readers, and two validated alternative parts with documented functional and application differences.
Technical Context
The MAX3001EEUP implements a passive-bidirectional architecture that eliminates the need for external direction control signals - each channel automatically detects and translates signal transitions in either direction (VL ↔ VCC). Its input thresholds are ratiometric (VIHL = 2/3×VL, VIHC = 2/3×VCC), ensuring robust operation across wide VL (+1.2V to +5.5V) and VCC (+1.65V to +5.5V) ranges.
It features an active-low EN pin that places all eight I/O VCC lines in high-impedance three-state while pulling down I/O VL lines via internal 6kΩ resistors. Shutdown supply currents are guaranteed <2µA from both VCC and VL rails, and propagation delays are specified at ≤50ns (I/O VL → I/O VCC) and ≤65ns (I/O VCC → I/O VL) under 50pF load conditions.
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 timing skew. |
| Supply Range (VL) | +1.2V to +5.5V - supports direct interfacing with 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic domains on the low-voltage side. |
| Supply Range (VCC) | +1.65V to +5.5V - ensures compatibility with 1.8V+ systems while preventing damage from sub-1.65V VCC. |
| ESD Protection | ±15kV HBM on I/O VCC pins - protects against handling and system-level ESD events in exposed interfaces like cellphone cradles. |
| Shutdown Current | <2µA from both VCC and VL - allows integration into battery-powered devices requiring ultra-low quiescent power during sleep modes. |
| Propagation Delay | ≤50ns (VL→VCC), ≤65ns (VCC→VL) at 50pF - ensures timing predictability in synchronous serial links with tight setup/hold windows. |
| Channel Count | 8 independent bidirectional channels - matches standard SPI bus width (MOSI/MISO/SCLK/CS ×2) or dual 4-bit parallel buses. |
Pinout & Package
MAX3001EEUP is housed in a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed thermal pad (EP) connected to GND. 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 I/O VL pins (1,3–9) reference VL; all I/O VCC pins (12–18,20) reference VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,3–9 (I/O VL1–8) | Bidirectional I/O referenced to VL | Accepts or drives logic signals at VL domain voltage; auto-senses direction per transition. |
| 10 (EN) | Active-low enable input | Pulling low disables I/O VCC outputs (three-state) and activates 6kΩ pulldowns on I/O VL lines. |
| 11 (GND) | Ground reference | Common return path for VL, VCC, and I/O; must be low-impedance for noise immunity. |
| 12–18,20 (I/O VCC8–1) | Bidirectional I/O referenced to VCC | Translates and drives signals at VCC domain; level-shifted output of corresponding I/O VL pin. |
| 19 (VCC) | High-side supply input | Must be bypassed with 0.1µF capacitor to GND; powers internal translator circuitry and VCC-side I/O drivers. |
| 2 (VL) | Low-side supply input | Must be bypassed with 0.1µF capacitor to GND; sets logic thresholds and powers VL-side I/O circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108PWR | 8-channel, 1.2V–3.6V VL/VCC range; 100Mbps max; no ±15kV ESD; requires external pullups for weak-drive scenarios. | Targeted at high-speed digital buses (e.g., I²C, JTAG); not qualified for harsh ESD environments like consumer docks. | Select when >10Mbps speed is required and ESD exposure is controlled; avoid where ±15kV HBM is mandated. |
| SN74AVC8T245RHLR | 8-channel, unidirectional (DIR pin required); 3.6V max VCC; 24mA drive strength; no integrated ESD beyond standard HBM. | Used in board-to-board interconnects with fixed data flow direction; unsuitable for true bidirectional protocols like SPI full-duplex. | Choose for cost-sensitive, unidirectional applications with strong local drivers; not a drop-in replacement for MAX3001EEUP's bidirectional operation. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, MAX3001EEUP uniquely combines guaranteed 4Mbps bidirectional operation, ±15kV HBM ESD on VCC I/Os, and 1.2V VL support - making it the only option qualified for ESD-prone, mixed-voltage SPI interfaces in portable consumer electronics.

FAQ
What is the maximum guaranteed data rate for MAX3001EEUP?
The MAX3001EEUP guarantees a 4Mbps data rate across its full operating voltage range (+1.65V ≤ VCC ≤ +5.5V, +1.2V ≤ VL ≤ VCC) and temperature range (–40°C to +85°C). This specification is validated under 50pF capacitive load conditions and ensures reliable SPI and MICROWIRE operation with timing margin. The MAX3001EEUP achieves this using a one-shot accelerator output stage optimized for fast edge response without external direction control.
Does MAX3001EEUP require a direction control signal?
No, MAX3001EEUP does not require a direction control signal. It uses a proprietary passive-bidirectional architecture that automatically detects and translates signal transitions in either direction (VL ↔ VCC) on each of its eight channels. This eliminates the need for external DIR pins, reduces PCB routing complexity, and removes firmware overhead associated with direction management - a key advantage over unidirectional translators like SN74AVC8T245RHLR.
What is the ESD rating of MAX3001EEUP and where is it applied?
MAX3001EEUP provides ±15kV Human Body Model (HBM) ESD protection specifically on all I/O VCC pins (pins 12–18 and 20), as confirmed in the Absolute Maximum Ratings and Detailed Description sections of the official datasheet. This protection is active in normal operation, three-state mode, and shutdown - enabling safe use in externally accessible interfaces such as smart card slots and cellphone docking connectors without additional TVS components.
Can MAX3001EEUP operate with VL = 1.2V and VCC = 5.5V simultaneously?
Yes, MAX3001EEUP is fully specified to operate with VL = +1.2V and VCC = +5.5V simultaneously. Its input thresholds scale ratiometrically (VIHL = 2/3×VL, VIHC = 2/3×VCC), ensuring correct logic interpretation across this extreme voltage ratio. The device also tolerates VL ≥ VCC during power-up without damage - a critical feature for asynchronous supply sequencing in battery-powered systems.
What happens to the I/O pins when the EN pin is pulled low on MAX3001EEUP?
When EN is pulled low on MAX3001EEUP, 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 isolates the VCC-side bus while maintaining defined logic-low states on the VL side - ideal for shared-bus arbitration and low-power sleep modes in portable communication devices.
