Product details
Overview
MAX3025EUD from Maxim Integrated is a quad-channel unidirectional logic-level translator IC designed for high-speed voltage translation between 1.2V–3.6V domains in multivoltage systems. It supports guaranteed 100Mbps data transfer when VL ≥ 1.8V, features dual enable inputs (EN/EN), operates over –40°C to +85°C, and delivers bidirectional tri-state control with ultra-low 0.1µA VL supply current in disabled mode - used in portable GPS receivers and SPI-based sensor interfaces.
For engineers reviewing the MAX3025EUD datasheet, MAX3025EUD pinout, MAX3025EUD application, or MAX3025EUD equivalent, this page provides verified functional identity, confirmed TSSOP-14 package mapping, validated 3×VL→VCC / 1×VCC→VL channel configuration, real-world timing parameters (tPLH ≤ 6.5ns), and two manufacturer-confirmed alternative parts with documented electrical and directional differences.
Technical Context
The MAX3025EUD implements a one-shot accelerator output architecture that activates only during signal transitions, minimizing quiescent power while enabling fast edge rates (tR/tF ≤ 4ns at 40pF). Its dual enable logic (EN active-high, EN active-low) allows flexible system-level control of tri-state behavior on both VL and VCC I/O banks independently.
It supports asymmetric level translation: three channels translate from VL domain to VCC domain (IVL1–VL3 → OVCC1–VCC3), and one channel translates from VCC to VL (IVCC4 → OVL4). Input thresholds are defined as fractions of respective supply rails (VIHL = 2/3 × VL, VIHC = 2/3 × VCC), ensuring robust noise margins across voltage combinations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 100Mbps guaranteed when VL ≥ 1.8V; 80Mbps supported down to VL = 1.2V - enables high-speed SPI/MICROWIRE interface bridging. |
| Supply Range | VCC: +1.65V to +3.6V; VL: +1.2V to (VCC − 0.4V) - supports translation between 1.8V ASICs and 3.3V microcontrollers. |
| Tri-State Supply Current | VCC: 0.03µA; VL: 0.1µA - enables ultra-low-power sleep modes in battery-powered devices. |
| Propagation Delay | I/OVL→VCC: 6.5ns max; I/OVCC→VL: 6ns max (CLOAD = 15pF) - ensures timing-critical signal integrity in synchronous interfaces. |
| Output Impedance | I/OVL: 12.5Ω; I/OVCC: 18.5Ω - matches standard CMOS loads without external termination. |
| Enable Logic | EN (active-high), EN (active-low); both required for normal operation in TSSOP package - prevents accidental tri-state activation. |
Pinout & Package
MAX3025EUD is housed in a 14-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed thermal pad. Pin assignments are fully validated per Maxim's datasheet Rev 1 (19-3266).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 13 | IVL1, IVL2, IVL3, IVCC4 | Unidirectional inputs referenced to VL (pins 1–3) or VCC (pin 13) - accept standard CMOS logic levels from source domain. |
| 4, 5, 6, 14 | OVCC1, OVCC2, OVCC3, OVL4 | Unidirectional outputs referenced to VCC (pins 4–6) or VL (pin 14) - drive destination logic with translated voltage levels. |
| 7, 8 | EN, EN | Complementary enable inputs: EN must be high (VL), EN must be low (GND) for active operation - eliminates floating control states. |
| 9, 10, 11, 12 | I/OVL4, I/OVCC3, GND, VCC | Unused I/O (pin 9), reserved I/O (pin 10), ground (pin 11), and main VCC supply (pin 12) - pin 9 is N.C. per MAX3025-specific configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional tri-state control via dual enables | EN and EN together define four operating modes (per Table 2), enabling precise power-gating of all I/Os without leakage path conflicts. |
| One-shot accelerator output stage | Reduces dynamic power by activating only during signal transitions - cuts switching current vs. always-on translators. |
| Asymmetric channel mapping (3:1) | Three VL→VCC and one VCC→VL paths match common interface topologies like 3-wire SPI with separate chip-select return. |
| Guaranteed 100Mbps at VL ≥ 1.8V | Meets timing requirements for high-speed serial buses without requiring external clock conditioning or retiming. |
| Robust power sequencing tolerance | Withstands VL ≥ VCC during startup/shutdown and sources up to 40mA per VL-side load without latch-up. |
Applications
| SPI Interface Bridging | Low-Power Sensor Hub |

Use Scenario: Interfacing a 1.8V MEMS sensor array to a 3.3V host MCU via SPI bus with separate CS# and MISO lines. IC Role / Device Role / Timing Role: Translates MOSI, SCLK, and CS# (VL→VCC) while returning MISO (VCC→VL) - handles full-duplex timing alignment. Use Value: Eliminates need for discrete level-shifting resistors or additional buffers; maintains 100Mbps throughput with <6.5ns propagation delay. |
Use Scenario: Power-managed wearable device where sensor subsystem sleeps while host remains active. IC Role / Device Role / Timing Role: Enables tri-state isolation of all sensor I/Os during sleep using coordinated EN/EN signals - reduces VL supply current to 0.1µA. Use Value: Extends battery life by cutting idle current vs. always-on translators; supports rapid wake/sync without reinitialization. |
| Portable GPS Receiver | Industrial POS Terminal |
|
Use Scenario: Connecting a 1.2V GPS baseband IC to a 3.3V application processor UART and GPIOs. IC Role / Device Role / Timing Role: Translates UART TX/RX and control signals (e.g., PPS, RESET) across voltage domains with sub-7ns skew. Use Value: Meets tight UART timing budgets (e.g., 115.2kbps with margin); avoids signal integrity degradation from RC filtering. |
Use Scenario: Integrating legacy 5V peripherals (e.g., magnetic stripe reader) into a modern 1.8V/3.3V embedded controller platform. IC Role / Device Role / Timing Role: Provides isolated, direction-controlled level shifting for bidirectional data and status lines in noisy retail environments. Use Value: Prevents ground-loop interference via galvanically separated I/O banks; withstands ±0.3V input overvoltage relative to supplies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3024EUD | 4× VL→VCC only (no VCC→VL path); identical TSSOP-14 package and enable logic. | Requires external translator for return-path signals (e.g., MISO, ACK); unsuitable for full-duplex interfaces. | Select when only uplink translation is needed and board layout prioritizes pin compatibility over bidirectional support. |
| MAX3026EUD | 2× VL→VCC + 2× VCC→VL; same package, supply ranges, and timing specs. | Matches symmetric protocols (e.g., I²C with pull-ups on both sides); higher channel symmetry but lower VL→VCC count than MAX3025EUD. | Select when balanced bidirectional traffic dominates and 3:1 asymmetry is unnecessary. |
Compared with MAX3024EUD and MAX3026EUD, the MAX3025EUD uniquely satisfies mixed-direction interfaces requiring exactly three uplink and one downlink channel - reducing component count versus combining multiple smaller translators while maintaining TSSOP-14 footprint compatibility.

FAQ
What is the exact channel configuration of the MAX3025EUD?
The MAX3025EUD implements three unidirectional level-shifting channels from the VL domain to the VCC domain (IVL1–VL3 → OVCC1–VCC3) and one channel from VCC to VL (IVCC4 → OVL4). This 3:1 asymmetry is fixed per the MAX3025EUD ordering code and differs from other variants like MAX3024EUD (4:0) or MAX3026EUD (2:2). The MAX3025EUD pinout confirms this mapping in its TSSOP-14 package.
Does the MAX3025EUD support operation with VL = 1.2V?
Yes, the MAX3025EUD supports VL as low as +1.2V (with VCC ≥ VL + 0.4V), but its guaranteed 100Mbps data rate applies only when VL ≥ 1.8V. At VL = 1.2V, the maximum supported data rate is 80Mbps per the datasheet's Table 1. All electrical characteristics - including input thresholds (VIHL = 2/3 × VL) and output drive - remain valid across the full VL range.
How do the EN and EN pins function on the MAX3025EUD?
On the MAX3025EUD (TSSOP package), EN is an active-high enable and EN is an active-low enable. Both must be asserted simultaneously for normal operation: EN = VL (high) and EN = GND (low). If either is violated, all I/Os enter tri-state. This dual-signal requirement prevents unintended activation due to noise or floating nodes - a key reliability feature confirmed in Table 2 of the MAX3025EUD datasheet.
What is the thermal performance of the MAX3025EUD in TSSOP package?
The MAX3025EUD in 14-pin TSSOP has a continuous power dissipation rating of 727mW at +70°C, derating by 9.1mW/°C above that temperature. Its junction-to-ambient thermal resistance (θJA) is not explicitly specified, but the package's exposed pad (visible in Maxim's TSSOP4.40mm.EPS drawing) supports PCB-level thermal relief. Operation is rated from –40°C to +85°C ambient, with maximum junction temperature limited to +150°C.
Can the MAX3025EUD replace a MAX3023EUD in an existing design?
No - the MAX3025EUD and MAX3023EUD are not functionally interchangeable. The MAX3023EUD is a bidirectional quad translator (4× VL↔VCC), while the MAX3025EUD is unidirectional with asymmetric 3:1 channel mapping. Their pinouts differ significantly: MAX3023EUD uses pins 1–6 for I/OVL1–VL4, whereas MAX3025EUD assigns pins 1–3 and 13 as inputs only. Direct substitution would require PCB redesign and firmware logic changes.
