Product details
Overview
The MAX3000EEUP+ from Maxim Integrated is an 8-channel bidirectional logic-level translator IC designed for multivoltage system interfacing between +1.2V and +5.5V domains. It operates with guaranteed 230kbps data rate, supports ±15kV HBM ESD protection on I/O VCC lines, draws only 0.1µA supply current in shutdown mode, and is packaged in a 20-pin TSSOP. It enables robust signal translation in portable communication devices requiring low-power, high-ESD-resilience level shifting.
For engineers reviewing the MAX3000EEUP+ datasheet, MAX3000EEUP+ pinout, MAX3000EEUP+ application, or MAX3000EEUP+ equivalent, this page delivers verified electrical specifications, validated bidirectional timing behavior, confirmed TSSOP package mapping, and real-world use cases in SPI/MICROWIRE interfaces and smart card readers - all derived from Maxim's official documentation.
Technical Context
The MAX3000EEUP+ implements a directionless bidirectional architecture that eliminates the need for external control signals to manage data flow direction. Its dual-supply operation (VL = +1.2V to +5.5V, VCC = +1.65V to +5.5V) enables seamless translation between low-voltage ASICs/PLDs and higher-voltage systems without voltage sequencing constraints.
It features an active EN input that places all eight I/O VCC pins in three-state while enabling 6kΩ pulldowns on I/O VL pins during shutdown, reducing both VCC and VL supply currents to <2µA. Input thresholds are defined as fractions of supply rails (VIHL/VILL = 2/3×VL / 1/3×VL; VIHC/VILC = 2/3×VCC / 1/3×VCC), ensuring predictable switching across operating voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 230kbps guaranteed - ensures reliable UART, I²C, and low-speed SPI translation without timing margin violations. |
| Supply Voltage Range (VL) | +1.2V to +5.5V - supports direct interface with 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic domains on the low-side. |
| Supply Voltage Range (VCC) | +1.65V to +5.5V - compatible with standard microcontroller I/O rails and legacy 5V systems. |
| ESD Protection (I/O VCC) | ±15kV HBM - provides robust handling for externally routed signals in handheld and cradle applications. |
| Shutdown Supply Current | <2µA from both VCC and VL - enables ultra-low-power sleep modes in battery-operated devices. |
| Propagation Delay (I/O VL → I/O VCC) | 1000ns max - defines worst-case latency for bidirectional data transfer at 230kbps under full load. |
| Channel Count | 8 independent bidirectional channels - allows parallel translation of data/address/control buses in compact designs. |
Pinout & Package
MAX3000EEUP+ is housed in a 20-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad (EP), optimized for thermal performance and PCB space efficiency in portable electronics.
| 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 domain (e.g., 1.8V ASIC); tolerate VL as low as +1.2V. |
| 2 (VL) | Low-side supply input | Must be bypassed to GND with 0.1µF capacitor; sets logic thresholds for VL-side I/Os. |
| 10 (EN) | Enable control input | Pull low to disable I/O VCC outputs (three-state) and activate 6kΩ pulldowns on I/O VL pins. |
| 11 (GND) | Ground reference | Common return path for both VL and VCC supplies; connect exposed pad to GND for thermal stability. |
| 12–18, 20 (I/O VCC1–I/O VCC8) | Bidirectional I/O referenced to VCC | Interface with higher-voltage domain (e.g., 3.3V MCU); output swing is VCC − 0.4V / 0.4V. |
| 19 (VCC) | High-side supply input | Must be bypassed to GND with 0.1µF capacitor; defines logic thresholds and output drive strength. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3001EEUP+ | 4Mbps guaranteed data rate; identical pinout and package; same ±15kV ESD rating. | Required where higher-speed SPI or UART links exceed 230kbps but remain below 4Mbps. | Select MAX3001EEUP+ when system timing budget demands faster propagation (50ns vs. 1000ns max) and higher throughput. |
| TXB0108PWR | Unidirectional architecture per channel; no EN pin; 3.6V max VCC; no ±15kV ESD rating. | Suitable for fixed-direction buses (e.g., GPIO expansion), but not for I²C or hot-plug scenarios requiring bidirectionality and ESD hardening. | Choose TXB0108PWR only for cost-sensitive, non-ESD-critical, unidirectional applications with ≤3.6V VCC. |
Compared with MAX3001EEUP+, the MAX3000EEUP+ trades speed for lower dynamic power and simpler driver requirements at 230kbps, while both share identical ESD robustness and package compatibility; versus TXB0108PWR, MAX3000EEUP+ provides true bidirectionality, superior ESD protection, and broader voltage support - critical for portable and industrial edge devices.

FAQ
What is the maximum guaranteed data rate for MAX3000EEUP+?
The MAX3000EEUP+ guarantees a data rate of 230kbps across its full operating temperature range (−40°C to +85°C) and supply voltage ranges (VL = +1.2V to +5.5V, VCC = +1.65V to +5.5V). This specification is validated per Maxim's datasheet timing characteristics table and applies under standard test conditions (RS = 50Ω, CVCC/CVL = 50pF).
Does MAX3000EEUP+ support bidirectional translation without a direction control pin?
Yes, the MAX3000EEUP+ uses a proprietary bidirectional architecture that requires no external direction pin. Data flows automatically from VL to VCC or VCC to VL depending on which side drives the signal - making it ideal for I²C, SMBus, and other open-drain or bidirectional protocols where adding direction logic is impractical.
What ESD protection does MAX3000EEUP+ provide, and on which pins?
The MAX3000EEUP+ provides ±15kV Human Body Model (HBM) ESD protection specifically on all I/O VCC pins (pins 12–18 and 20), as confirmed in Maxim's datasheet Absolute Maximum Ratings and Detailed Description sections. This protection remains effective in normal operation, three-state mode, and shutdown - eliminating latch-up risk after ESD events.
Can MAX3000EEUP+ operate with VL higher than VCC during power-up?
Yes, the MAX3000EEUP+ tolerates VL ≥ VCC during power-up sequencing without damage, as explicitly stated in the datasheet Note 2 and Detailed Description section. However, for stable operation, VL must be ≤ VCC during normal use to ensure correct threshold referencing and avoid undefined logic states.
What is the function of the EN pin on MAX3000EEUP+?
On the MAX3000EEUP+, the EN pin (pin 10) controls output enable state: when pulled low, all eight I/O VCC pins enter high-impedance three-state mode, while all eight I/O VL pins activate internal 6kΩ pulldown resistors. Driving EN high (to VL) restores full bidirectional operation - enabling low-power sleep modes in portable systems.
