Product details
Overview
MAX3012EUP+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 across full operating voltage range, features EN-controlled three-state outputs on VCC side and 6kΩ pulldowns on VL side during shutdown, and delivers ±15kV HBM ESD protection on I/O VCC lines. It is used in portable POS systems and smart card readers requiring robust level shifting with low quiescent current.
For engineers reviewing the MAX3012EUP+T datasheet, MAX3012EUP+T pinout, MAX3012EUP+T application, or MAX3012EUP+T equivalent, key selection criteria include its 20Mbps timing performance at 1.8V–3.3V operation, EN-driven unidirectional control architecture, 0.1µA shutdown supply current, and TSSOP-20 package compatibility with space-constrained embedded interfaces.
Technical Context
The MAX3012EUP+T implements a unidirectional level-shifting architecture where signals flow exclusively from VL-side inputs (IVL1–IVL8) to VCC-side outputs (OVCC1–OVCC8), with no bidirectional capability. Its enable input (EN) directly controls output state: when low, all OVCC outputs enter high-impedance mode while OVL outputs remain active with internal 6kΩ pulldowns.
It operates across VL = +1.2V to +5.5V and VCC = +1.65V to +5.5V, with guaranteed 20Mbps data rate over the entire specified voltage range and up to 35Mbps under +2.5V ≤ VL ≤ VCC ≤ +3.3V conditions. Propagation delay is 15ns (typ) for both I/OVL→I/OVCC and I/OVCC→I/OVL directions under 15pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 20Mbps guaranteed across full VL/VCC operating range; enables high-speed SPI/MICROWIRE interface bridging between low-voltage ASICs and 3.3V/5V systems. |
| Supply Voltage Range | VL: +1.2V to +5.5V; VCC: +1.65V to +5.5V - supports translation from sub-1.8V logic (e.g., 1.2V FPGA I/O) to standard 3.3V/5V buses. |
| Shutdown Current | <0.1µA typical from both VL and VCC supplies when EN = low - critical for battery-powered devices requiring ultra-low leakage during sleep. |
| ESD Protection | ±15kV HBM on I/O VCC pins - ensures robustness in handheld devices exposed to frequent human handling and connector insertion. |
| Propagation Delay | 15ns (typ) I/OVL→I/OVCC and I/OVCC→I/OVL at 15pF load - meets timing budgets for 20Mbps serial links with margin. |
| Channel Count | 8 independent unidirectional channels - sufficient for full-byte parallel translation or multi-signal bus interfacing (e.g., 8-bit data + control). |
| Output Configuration | EN-controlled three-state on VCC side; 6kΩ pulldown on VL side during shutdown - prevents floating nodes and ensures defined logic states in power-gated subsystems. |
Pinout & Package
MAX3012EUP+T is housed in a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin numbering follows standard TSSOP convention; EP must be connected to GND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1,3–9 | I/O VL1–I/O VL8 | VL-referenced inputs (IVL1–IVL8); accept 1.2V–5.5V logic; drive internal translator core. |
| 2 | VL | Logic-side supply input; bypass to GND with 0.1µF capacitor; sets low-voltage domain reference. |
| 10 | EN | Enable input referenced to VL; low = disable OVCC outputs (three-state), activate OVL pulldowns. |
| 11 | GND | Common ground reference for both VL and VCC domains; connects to EP for thermal path. |
| 12–18,20 | I/O VCC8–I/O VCC1 | VCC-referenced outputs (OVCC1–OVCC8); deliver translated logic levels (VCC − 0.4V high, 0.4V low). |
| 19 | VCC | VCC-side supply input; bypass to GND with 0.1µF capacitor; sets high-voltage domain reference. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional 8-channel translation | Enables clean, isolated signal flow from low-voltage controllers (e.g., 1.2V/1.8V SoC GPIO) to higher-voltage peripherals without direction-pin overhead or contention risk. |
| 20Mbps guaranteed data rate | Meets timing requirements for high-speed serial interfaces including SPI clocked up to 10MHz with setup/hold margin. |
| 0.1µA shutdown supply current | Reduces system standby power in portable devices - e.g., extends battery life in smart card readers by >3 years in deep-sleep mode. |
| ±15kV HBM ESD on I/O VCC | Eliminates need for external TVS diodes on host-facing signal lines, simplifying PCB layout and BOM for consumer-grade handhelds. |
| TSSOP-20 package with exposed pad | Provides thermal reliability in compact industrial enclosures and enables reflow-compatible assembly without special process requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108PWR | Bidirectional auto-sensing architecture; no EN pin; 1.2V–3.6V VL/VCC range; 100Mbps max; 1.5µA quiescent current. | Requires no direction control but lacks EN-driven shutdown; unsuitable where precise power-gating of outputs is required. | Select TXB0108PWR only if bidirectional operation and higher speed are needed, and ultra-low shutdown current is not critical. |
| SN74AVCH8T245RHLR | Configurable VREF-based translation; 1.2V–3.6V I/O range; 24mA drive strength; 10µA quiescent current; OE-controlled three-state. | Offers stronger drive and configurable thresholds but consumes 100× more shutdown current than MAX3012EUP+T. | Choose SN74AVCH8T245RHLR when driving heavy capacitive loads (>30pF) or when VREF flexibility outweighs battery-life impact. |
Compared with TXB0108PWR and SN74AVCH8T245RHLR, MAX3012EUP+T uniquely combines 20Mbps unidirectional translation, ±15kV ESD hardening, and sub-0.1µA shutdown - making it optimal for safety-critical, battery-sensitive, and high-reliability portable interfaces where direction control and zero-leakage sleep are mandatory.

FAQ
What is the maximum data rate supported by MAX3012EUP+T under typical operating conditions?
MAX3012EUP+T guarantees 20Mbps operation across its full VL (+1.2V to +5.5V) and VCC (+1.65V to +5.5V) voltage ranges. At optimized conditions - specifically +2.5V ≤ VL ≤ VCC ≤ +3.3V with 15pF load - it achieves up to 35Mbps, as confirmed in the Timing Characteristics table of the official datasheet. This makes MAX3012EUP+T suitable for high-speed SPI and MICROWIRE interfaces in portable electronics.
Does MAX3012EUP+T support bidirectional signal translation?
No, MAX3012EUP+T is strictly unidirectional: signals translate only from VL-side inputs (IVL1–IVL8) to VCC-side outputs (OVCC1–OVCC8). Unlike MAX3000E/MAX3001E/MAX3002/MAX3003, it does not support reverse-direction translation. This architecture eliminates contention risk and simplifies control in systems where data flow direction is fixed - a key design choice reflected in the MAX3012EUP+T's dedicated EN pin and internal pulldown configuration.
How does the EN pin function in MAX3012EUP+T, and what happens to the I/O pins during shutdown?
In MAX3012EUP+T, pulling EN low disables all eight OVCC outputs (I/O VCC1–I/O VCC8) by placing them in high-impedance three-state mode, while simultaneously activating 6kΩ internal pulldown resistors on all eight OVL outputs (I/O VL1–I/O VL8). This ensures defined logic-low states on the VL side and prevents floating nodes on the VCC side - a critical feature for power-gated subsystems. The shutdown supply current drops to <0.1µA from both VL and VCC rails.
What package type and footprint does MAX3012EUP+T use, and is thermal management supported?
MAX3012EUP+T uses a 20-pin TSSOP package (5.0mm × 6.5mm, 0.65mm pitch) with an exposed pad (EP) that must be soldered to a GND plane for optimal thermal performance. The datasheet specifies a thermal resistance θJA of 7.0mW/°C above +70°C derating, enabling reliable operation up to +85°C ambient. This package is compatible with standard reflow processes and widely supported by PCB design tools and contract manufacturers.
Is MAX3012EUP+T compatible with 1.2V logic systems, and what is the minimum VL supply voltage?
Yes, MAX3012EUP+T fully supports 1.2V logic systems: its VL supply range is explicitly specified as +1.2V to +5.5V, and all electrical characteristics - including input thresholds (VIHL = 2/3 × VL, VILL = 1/3 × VL) and output drive (VOHL = VL − 0.4V, VOLL = 0.4V) - are guaranteed down to VL = +1.2V. This allows seamless integration with modern ultra-low-voltage ASICs, FPGAs, and application processors without level-shifter cascading.
