Product details
Overview
MAX3004EUP+ from Maxim Integrated is an 8-channel unidirectional logic-level translator enabling voltage translation between VL = +1.2V to +5.5V and VCC = +1.65V to +5.5V domains. It supports guaranteed 20Mbps data rate, features EN-controlled three-state outputs on VCC side with 6kΩ pulldowns on VL side during shutdown, and operates across –40°C to +85°C for portable communication and smart card reader interfaces.
For engineers reviewing the MAX3004EUP+ datasheet, MAX3004EUP+ pinout, MAX3004EUP+ application, or MAX3004EUP+ equivalent, key selection criteria include its unidirectional VL→VCC/VCC→VL translation capability, 20Mbps timing performance at 15ns rise/fall times (CL = 15pF), ±15kV ESD protection on I/O VCC lines, and compatibility with low-voltage ASIC/PLD interfacing in space-constrained TSSOP-20 layouts.
Technical Context
The MAX3004EUP+ implements unidirectional level translation using a passive FET-based architecture without direction control pins, supporting signal flow either VL → VCC or VCC → VL per channel. Its enable input (EN) directly controls output state on the VCC side while activating internal 6kΩ pulldown resistors on all eight VL-side I/Os when pulled low.
It accepts asymmetric supply rails - VL as low as +1.2V and VCC as low as +1.65V - and guarantees 20Mbps operation across the full voltage range. Timing parameters including tRVCC, tFVCC, tRVL, tFVL, and propagation delays (I/OVL-VCC, I/OVCC-VL) are specified down to 15ns under 15pF load conditions at +2.5V ≤ VL ≤ VCC ≤ +3.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 20Mbps guaranteed over full operating voltage range; enables high-speed SPI/MICROWIRE interface bridging |
| VL Supply Range | +1.2V to +5.5V; supports direct connection to 1.2V/1.8V/2.5V/3.3V/5V logic domains |
| VCC Supply Range | +1.65V to +5.5V; ensures interoperability with legacy 3.3V/5V systems and modern low-power controllers |
| ESD Protection | ±15kV HBM on I/O VCC lines; eliminates need for external TVS diodes in handheld device I/O routing |
| Shutdown Current | <2µA on both VCC and VL supplies when EN = low; critical for battery-powered GPS and POS systems |
| Rise/Fall Time | 15ns max (CL = 15pF, +2.5V ≤ VL ≤ VCC ≤ +3.3V); meets timing closure for 20MHz clocked serial buses |
| Propagation Delay | 15ns max (I/OVL-VCC and I/OVCC-VL, CL = 15pF); ensures deterministic latency in real-time sensor data links |
Pinout & Package
MAX3004EUP+ is housed in a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed pad for thermal management. 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 eight VL-side I/Os occupy pins 1–9 (excluding VL and GND), and all eight VCC-side I/Os occupy pins 12–20 (excluding VCC and GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–I/O VL8 | VL-referenced bidirectional I/O (unidirectional mode) | Accept inputs or drive outputs referenced to VL; internally pulldown to GND when EN = low |
| I/O VCC1–I/O VCC8 | VCC-referenced bidirectional I/O (unidirectional mode) | Three-state when EN = low; active high/low outputs when EN = VL; compatible with 5V-tolerant microcontrollers |
| VL | Logic input supply rail | Bypass to GND with 0.1µF capacitor; sets low-voltage domain threshold (VIHL = 2/3×VL, VILL = 1/3×VL) |
| VCC | Output supply rail | Bypass to GND with 0.1µF capacitor; defines high-voltage logic levels (VIHC = 2/3×VCC, VILC = 1/3×VCC) |
| EN | Enable control input | Pull low to disable VCC-side outputs and activate VL-side 6kΩ pulldowns; driven to VL for normal operation |
| GND | Common reference | Return path for both supply domains; must be low-impedance connection to minimize ground bounce |
Key Features

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; 1.2V–3.6V I/O range; 100Mbps typical | Requires no enable control but lacks shutdown current <2µA; unsuitable for battery-critical GPS modules | Select MAX3004EUP+ when precise EN-controlled shutdown and ±15kV ESD are mandatory |
| SN74AVC8T245RHLR | Direction-controlled (DIR pin); 1.2V–3.6V I/O; 24mA drive strength; no integrated ESD beyond 2kV HBM | Needs external ESD protection for handheld use; higher quiescent current (~10µA) limits battery life | Choose MAX3004EUP+ for ESD-hardened, ultra-low-power, enable-gated designs in consumer portables |
Compared with TXB0108PWR and SN74AVC8T245RHLR, the MAX3004EUP+ uniquely delivers guaranteed 20Mbps unidirectional translation with sub-2µA shutdown, ±15kV I/O VCC ESD, and 1.2V VL support - making it optimal for space- and power-constrained portable electronics where reliability and low standby drain are non-negotiable.

FAQ
What is the maximum data rate supported by the MAX3004EUP+?
The MAX3004EUP+ guarantees 20Mbps operation across its full specified voltage range (+1.2V ≤ VL ≤ VCC ≤ +5.5V). At optimized conditions (+2.5V ≤ VL ≤ VCC ≤ +3.3V, CL = 15pF), it achieves up to 35Mbps. This makes the MAX3004EUP+ suitable for high-speed SPI, MICROWIRE, and UART interfaces in portable telecom and GPS applications where deterministic timing is critical.
Does the MAX3004EUP+ support bidirectional level translation?
No, the MAX3004EUP+ is a unidirectional level translator. Unlike the MAX3000E/MAX3001E/MAX3002/MAX3003, it does not support automatic bidirectional signal flow. The MAX3004EUP+ translates signals either VL → VCC or VCC → VL per channel, controlled by external logic - not internal sensing. This architecture simplifies timing analysis and eliminates shoot-through risk in fixed-path interfaces like smart card readers.
What is the function of the EN pin on the MAX3004EUP+?
On the MAX3004EUP+, the EN pin controls output enable state: when pulled low, all eight I/O VCC pins enter three-state (high-impedance), while all eight I/O VL pins activate internal 6kΩ pulldown resistors. Driving EN to VL enables normal translation. This feature allows precise power gating in battery-powered systems - e.g., disabling the MAX3004EUP+ during GPS sleep cycles to maintain sub-2µA system standby current.
Can the MAX3004EUP+ operate with VL = 1.2V and VCC = 3.3V simultaneously?
Yes, the MAX3004EUP+ is explicitly rated for VL = +1.2V to +5.5V and VCC = +1.65V to +5.5V, with VL ≤ VCC. Operation at VL = 1.2V and VCC = 3.3V is fully supported and validated in the datasheet's Electrical Characteristics table. Input thresholds scale with supply (VIHL = 2/3×VL = 0.8V, VIHC = 2/3×VCC = 2.2V), ensuring noise-immune logic recognition across this wide voltage combination.
Is the MAX3004EUP+ pin-compatible with other devices in the MAX3000E–MAX3012 family?
Yes, the MAX3004EUP+ shares identical 20-pin TSSOP pinout and terminal functions with MAX3000EEUP+, MAX3001EEUP+, and MAX3002EUP+. All use the same VL, VCC, GND, EN, and I/O VL/VCC pin assignments. However, functional differences exist: MAX3000E/MAX3001E are bidirectional; MAX3002 is bidirectional with 20Mbps; MAX3004–MAX3012 are unidirectional variants - so PCB layout reuse is possible, but firmware and signal routing must match the selected variant's directionality.
