Product details
Overview
MAX3004EUP+T from Maxim Integrated is an 8-channel unidirectional logic-level translator enabling voltage translation between VL (1.2V–5.5V) and VCC (1.65V–5.5V) domains, supporting guaranteed 20Mbps data rate, ±15kV HBM ESD protection on I/O VCC lines, and ultra-low 0.1µA shutdown current. It serves in SPI/MICROWIRE interfaces between low-voltage ASICs and 3.3V/5V systems.
For engineers reviewing the MAX3004EUP+T datasheet, MAX3004EUP+T pinout, MAX3004EUP+T application, or MAX3004EUP+T equivalent, key selection criteria include its unidirectional VL→VCC/VCC→VL translation capability, EN-controlled three-state outputs on I/O VCC side, pulldown resistors on I/O VL side during shutdown, and compatibility with TSSOP-20 PCB layouts for portable communication and smart card reader designs.
Technical Context
The MAX3004EUP+T implements unidirectional level translation without direction control pins, using dual-supply referenced I/O banks: eight I/O VL_ pins (1–8) referenced to VL and eight I/O VCC_ pins (1–8) referenced to VCC. Translation occurs only from one side to the other per channel, not bidirectionally.
Its EN input enables full three-state control of all I/O VCC_ outputs while activating 6kΩ internal pulldowns on all I/O VL_ pins. Timing performance is load- and voltage-dependent - achieving up to 35Mbps at +1.8V ≤ VL ≤ VCC ≤ +2.5V and 20Mbps across full operating range (1.2V–5.5V VL, 1.65V–5.5V VCC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 20Mbps guaranteed over full voltage range; up to 35Mbps at 1.8V–2.5V supply range - enables high-speed SPI and MICROWIRE interface bridging |
| Supply Range VL | +1.2V to +5.5V - supports direct interfacing with 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic families |
| Supply Range VCC | +1.65V to +5.5V - ensures compatibility with standard microcontroller I/O rails including 1.8V and above |
| ESD Protection | ±15kV HBM on I/O VCC_ pins - eliminates need for external TVS diodes in handheld and exposed-port applications |
| Shutdown Current | <0.1µA total (VCC + VL) when EN = low - critical for battery-powered portable POS and GPS devices |
| Propagation Delay | 15ns max (I/O VL_ → I/O VCC_) at 20Mbps, 50pF load - ensures timing margin in 20MHz clocked serial buses |
| Channel-to-Channel Skew | 5ns max - maintains signal integrity across all 8 channels in parallel data paths like memory expansion interfaces |
Pinout & Package
MAX3004EUP+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 10 is EN; pin 11 is GND; pin 19 is VCC; pin 20 is I/O VCC1. All I/O VL_ pins (1–9, excluding VL and GND) are on left side; all I/O VCC_ pins (12–20, excluding VCC and GND) are on right side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–I/O VL8 | Input/Output bank referenced to VL | Accept or drive signals at VL domain voltage; internally pulled down to GND via 6kΩ when EN = low |
| I/O VCC1–I/O VCC8 | Input/Output bank referenced to VCC | Three-state when EN = low; active high/low outputs referenced to VCC during normal operation |
| VL | Logic-side supply input | Must be bypassed with 0.1µF capacitor to GND; sets low-voltage logic threshold (VIHL = 2/3×VL) |
| VCC | High-side supply input | Must be bypassed with 0.1µF capacitor to GND; defines high-voltage logic thresholds (VIHC = 2/3×VCC) |
| EN | Enable control input | Pull low to disable I/O VCC_ outputs (three-state) and activate I/O VL_ pulldowns; tie to VL for normal operation |
| GND | Common reference | Return path for both VL and VCC supplies; connect exposed pad directly to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional translation architecture | Enables deterministic VL ↔ VCC signal flow per channel without direction pin - simplifies PCB routing and firmware control |
| EN-controlled three-state outputs | Allows dynamic bus isolation during system sleep or multiplexing - prevents contention in shared data lines |
| 6kΩ internal pulldown on I/O VL_ in shutdown | Ensures defined logic-low state on low-voltage side when disabled - avoids floating inputs and leakage-induced noise |
| Guaranteed 20Mbps operation over full voltage range | Supports reliable high-speed serial communication (e.g., SPI at 10MHz SCLK) across industrial temperature range (−40°C to +85°C) |
| ±15kV HBM ESD on I/O VCC_ pins | Meets IEC 61000-4-2 Level 4 requirements - eliminates external protection components in consumer and telecom front-end designs |

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; 32mA drive strength; 1.2V–3.6V I/O range only | Requires no enable control but lacks shutdown mode; unsuitable for asymmetric 1.2V↔5V translation | Select when bidirectional operation and minimal control logic are prioritized over wide voltage range and ultra-low shutdown current |
| SN74AVC8T245RHLR | Direction-controlled (DIR pin); 3.6V max VCC; 12mA drive; no integrated ESD protection beyond 2kV HBM | Needs external ESD protection for harsh environments; limited to ≤3.6V systems | Select when precise direction control and higher drive strength are required, and system-level ESD protection is already implemented |
Compared with TXB0108PWR and SN74AVC8T245RHLR, MAX3004EUP+T uniquely combines 1.2V–5.5V VL/VCC flexibility, ±15kV ESD hardening, and sub-µA shutdown - making it optimal for portable, battery-constrained, and externally exposed interfaces where voltage asymmetry and robustness are critical.

FAQ
What is the maximum data rate supported by MAX3004EUP+T under typical conditions?
The MAX3004EUP+T guarantees 20Mbps operation across its full specified voltage range (VL = 1.2V–5.5V, VCC = 1.65V–5.5V). At optimized conditions - specifically +1.8V ≤ VL ≤ VCC ≤ +2.5V with 15pF load - it achieves up to 30Mbps. Performance is load- and supply-dependent; actual achievable rate must be validated with target PCB capacitance and driver strength per the datasheet's timing equations.
Does MAX3004EUP+T support bidirectional level translation like MAX3002EUP+T?
No, MAX3004EUP+T is strictly unidirectional. Unlike the bidirectional MAX3002EUP+T, it translates signals only from VL-side to VCC-side or VCC-side to VL-side per channel, with no automatic direction sensing. Its architecture requires explicit signal flow definition in system design - making it suitable for fixed-path interfaces such as SPI master-to-peripheral links.
How does the EN pin function in MAX3004EUP+T, and what happens to the I/O pins during shutdown?
When EN is pulled low, MAX3004EUP+T places all eight I/O VCC_ pins in high-impedance three-state mode, while simultaneously enabling 6kΩ internal pulldown resistors on all eight I/O VL_ pins. This ensures defined logic-low states on the VL side and prevents bus contention on the VCC side - critical for power-gated subsystems in portable devices.
Can MAX3004EUP+T translate between 1.2V and 5V logic levels safely?
Yes, MAX3004EUP+T explicitly supports VL = +1.2V to +5.5V and VCC = +1.65V to +5.5V, with the constraint that VL ≤ VCC. Thus, 1.2V-to-5V translation is fully supported and validated. The device tolerates VL > VCC during power-up without damage, though sustained operation outside VL ≤ VCC is not recommended per datasheet specifications.
Is external ESD protection required when using MAX3004EUP+T in handheld applications?
No, external ESD protection is not required on the I/O VCC_ lines. MAX3004EUP+T integrates ±15kV Human Body Model (HBM) ESD protection on all I/O VCC_ pins - exceeding IEC 61000-4-2 Level 4 requirements. This eliminates the need for discrete TVS diodes in smartphone cradles, portable scanners, and other user-accessible interfaces.
