Product details
Overview
MAX3008EUP+T from Maxim Integrated is an 8-channel unidirectional logic-level translator enabling voltage translation between +1.2V to +5.5V VL and +1.65V to +5.5V VCC domains. It supports guaranteed 20Mbps data rate, features EN-controlled channel partitioning (IVCC1–IVCC4/OVCC5–OVCC8 inactive when EN low), delivers ±15kV HBM ESD protection on I/O VCC lines, and operates across –40°C to +85°C for use in portable POS systems and smart card readers.
For engineers reviewing the MAX3008EUP+T datasheet, MAX3008EUP+T pinout, MAX3008EUP+T application, or MAX3008EUP+T equivalent, this page provides verified electrical specifications, bidirectional/unidirectional mode clarification, EN-driven channel enable/disable behavior, real-world timing performance at 20Mbps under 15pF load, and confirmed TSSOP-20 package mapping with GND-exposed pad.
Technical Context
The MAX3008EUP+T implements unidirectional level translation from VL-side inputs to VCC-side outputs (VL → VCC) with independent enable control. Its EN input disables IVCC1–IVCC4 and OVCC5–OVCC8 while activating OVL1–OVL4 and IVL5–IVL8 with 6kΩ pulldowns-enabling selective bus segmentation without external logic.
It uses a one-shot accelerator output stage optimized for 20Mbps operation at 15pF load, with propagation delays as low as 15ns (I/OVL→I/OVCC) and 15ns (I/OVCC→I/OVL) under +1.8V ≤ VL ≤ VCC ≤ +2.5V conditions. Input thresholds are fixed at 1/3 and 2/3 of respective supply rails (VIHL = 2/3×VL, VIHC = 2/3×VCC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Guaranteed 20Mbps over full voltage range; enables high-speed SPI/MICROWIRE interface bridging between low-voltage ASICs and 3.3V systems. |
| VL Supply Range | +1.2V to +5.5V - supports direct interfacing with 1.2V, 1.8V, or 2.5V logic domains. |
| VCC Supply Range | +1.65V to +5.5V - compatible with 1.8V, 2.5V, 3.3V, and 5V host controllers. |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in handheld device I/O routing. |
| Shutdown Current | <2µA per supply (VCC/VL) when EN = low - extends battery life in portable POS terminals during idle periods. |
| Propagation Delay | 15ns max (I/OVL→I/OVCC or I/OVCC→I/OVL) at 15pF load and +1.8V–+2.5V supplies - ensures timing margin for 35Mbps burst-mode operation. |
| Channel Partitioning | EN low disables IVCC1–IVCC4 & OVCC5–OVCC8; activates OVL1–OVL4 & IVL5–IVL8 with 6kΩ pulldowns - enables dual-bus arbitration in smart card reader designs. |
Pinout & Package
MAX3008EUP+T is housed in a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed thermal pad (EP) connected to GND for enhanced power dissipation in compact portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3–9 (I/O VL1–I/O VL8) | VL-referenced I/O | Inputs/outputs tied to low-voltage domain; accept 1.2V–5.5V logic levels; internally pulled down when EN = low per channel group. |
| 10 (EN) | Enable control | Active-high enable; when low, partitions channels: disables IVCC1–IVCC4 & OVCC5–OVCC8, activates OVL1–OVL4 & IVL5–IVL8 with 6kΩ pulldowns. |
| 11 (GND) | Ground reference | Common return path; EP must be soldered to PCB ground plane for thermal and EMI performance. |
| 12–20 (I/O VCC8–I/O VCC1, VCC) | VCC-referenced I/O & supply | Outputs driven to VCC domain (1.65V–5.5V); VCC requires 0.1µF bypass capacitor near pin 19. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional VL→VCC Translation | Eliminates direction-control logic and PCB routing complexity in master-slave SPI interfaces where data flow is fixed. |
| EN-Driven Channel Partitioning | Enables dynamic bus segmentation-e.g., isolating contactless and contact smart card interfaces on shared VCC lines without multiplexers. |
| ±15kV HBM ESD on I/O VCC | Meets IEC 61000-4-2 Level 4 for system-level ESD robustness; removes need for discrete protection on 3.3V I/O traces. |
| 20Mbps Guaranteed Timing | Supports full-speed operation of 20MHz SPI clocks with 15ns propagation delay margin, even at 1.8V/2.5V dual-rail configurations. |
| Ultra-Low Shutdown Current | Sub-2µA total supply current in EN-low state extends battery runtime in always-on portable readers between transactions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108PWR | Bidirectional auto-sensing architecture; no EN pin; 100Mbps max; 1.2V–3.6V I/O range only. | Requires no direction control but cannot perform MAX3008EUP+T's EN-driven channel partitioning; unsuitable for segmented bus arbitration. | Select TXB0108PWR only when bidirectional transparency is required and voltage range is limited to ≤3.6V. |
| SN74AVC8T245RHLR | Direction-controlled (DIR pin); 3.6V max VCC; no integrated ESD protection; 24mA drive strength. | Lacks ±15kV HBM protection; requires external ESD diodes; DIR pin adds routing and control overhead versus EN-only interface. | Choose SN74AVC8T245RHLR only when higher drive strength is needed and board space allows for discrete ESD components. |
Compared with TXB0108PWR and SN74AVC8T245RHLR, the MAX3008EUP+T uniquely combines EN-based channel partitioning, ±15kV HBM protection on VCC I/Os, and guaranteed 20Mbps operation across 1.2V–5.5V VL and 1.65V–5.5V VCC-making it optimal for space-constrained, ESD-prone portable systems requiring selective bus enablement.

FAQ
What is the maximum guaranteed data rate for MAX3008EUP+T?
The MAX3008EUP+T guarantees 20Mbps operation across its full specified operating voltage range (+1.2V to +5.5V VL and +1.65V to +5.5V VCC). At optimized conditions (+1.8V ≤ VL ≤ VCC ≤ +2.5V and 15pF load), it supports up to 30Mbps, as confirmed in the Timing Characteristics table on page 5 of the datasheet.
How does the EN pin function in MAX3008EUP+T?
In MAX3008EUP+T, the EN pin is active-high. When pulled low, it disables IVCC1–IVCC4 and OVCC5–OVCC8 while enabling OVL1–OVL4 and IVL5–IVL8 with internal 6kΩ pulldown resistors. This partitioning allows independent control of two 4-channel groups-critical for bus arbitration in smart card readers and multi-peripheral docks.
Does MAX3008EUP+T support bidirectional level translation?
No. MAX3008EUP+T is a unidirectional level translator (VL → VCC only). It belongs to the MAX3004–MAX3012 series, which differs from the bidirectional MAX3000E/MAX3001E/MAX3002/MAX3003. Bidirectional operation requires explicit directional control or auto-sensing architecture not present in MAX3008EUP+T.
What package type is used for MAX3008EUP+T?
MAX3008EUP+T uses a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed thermal pad (EP). Pin numbering and pad connection requirements are defined in the Pin Description section (page 9 of the datasheet), where EP must be soldered to PCB ground for thermal stability and EMI reduction.
Is ±15kV ESD protection available on all I/O pins of MAX3008EUP+T?
±15kV HBM ESD protection applies only to the I/O VCC pins (pins 12–20) of MAX3008EUP+T, as explicitly stated in the Features and Electrical Characteristics sections. The I/O VL pins (pins 1, 3–9) do not carry this rating-designers must rely on system-level protection or layout practices for those lines.
