Product details
Overview
MAX3002EBP from Maxim Integrated is an 8-channel bidirectional logic-level translator IC enabling voltage translation between +1.2V to +5.5V (VL) and +1.65V to +5.5V (VCC) domains without direction control pins. It guarantees 20Mbps data rate across full voltage range, supports ±15kV HBM ESD protection on VCC-side I/Os, and draws only 0.1µA supply current in shutdown mode. It is used in SPI/MICROWIRE interfaces between low-voltage ASICs and 3.3V/5V systems.
For engineers reviewing the MAX3002EBP datasheet, MAX3002EBP pinout, MAX3002EBP application, or MAX3002EBP equivalent, key selection criteria include guaranteed 20Mbps operation at 1.8V–3.3V interface pairs, bidirectional architecture eliminating direction-control logic, ultra-low shutdown current (<2µA), 20-pin UCSP package footprint, and compatibility with portable communication and smart-card reader designs requiring robust ESD immunity.
Technical Context
The MAX3002EBP employs a passive-bidirectional MOSFET-based translation architecture that automatically senses signal direction on each channel - no external direction pin or control logic required. It operates with independent VL and VCC supplies, where VL sets low-voltage logic thresholds (VIHL = 2/3×VL, VILL = 1/3×VL) and VCC defines high-side thresholds (VIHC = 2/3×VCC, VILC = 1/3×VCC).
It features an active-low EN input that places all eight VCC-referenced I/Os into high-impedance three-state while enabling 6kΩ pulldowns on VL-referenced I/Os. Propagation delay is asymmetric: 15ns typical (I/O VL → I/O VCC) and 15ns typical (I/O VCC → I/O VL) under 15pF load at 1.8V–3.3V operation, supporting 35Mbps peak data rate in optimized conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 20Mbps guaranteed over full voltage range; up to 35Mbps at +1.8V ≤ VL ≤ VCC ≤ +2.5V with 15pF load |
| Supply Voltage Range | VL: +1.2V to +5.5V; VCC: +1.65V to +5.5V - enables interfacing 1.2V/1.8V ASICs with 3.3V/5V peripherals |
| ESD Protection | ±15kV HBM on I/O VCC pins - eliminates need for external TVS diodes in handheld and cradle applications |
| Shutdown Current | <2µA total (VCC + VL) when EN = low - critical for battery-powered GPS and POS systems |
| Propagation Delay | 15ns max (I/O VL ↔ I/O VCC) at 1.8V–3.3V, 15pF - ensures timing compliance in 20MHz SPI clock domains |
| Channel Count | 8 independent bidirectional channels - supports full 8-bit data bus translation or dual 4-line SPI buses |
| Logic Thresholds | VIL/VIH defined as 1/3 and 2/3 of respective supply - provides noise margin >30% at 1.8V/3.3V interface |
Pinout & Package
MAX3002EBP is packaged in a 20-bump UCSP (Ultra Compact Silicon Package) measuring 2.5mm × 2.5mm with 0.5mm pitch, featuring an exposed pad for thermal and electrical grounding. The UCSP variant uses bump mapping aligned to TSSOP pinout for layout compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O VL1–I/O VL8 | VL-referenced bidirectional I/O | Connect to low-voltage domain signals (e.g., 1.8V ASIC GPIO); tolerate 0.3V beyond VL rail |
| I/O VCC1–I/O VCC8 | VCC-referenced bidirectional I/O | Connect to higher-voltage system (e.g., 3.3V microcontroller SPI lines); tolerate VCC + 0.3V |
| VL | Low-voltage supply input | Bypass to GND with 0.1µF capacitor; sets logic thresholds and powers VL-side circuitry |
| VCC | High-voltage supply input | Bypass to GND with 0.1µF capacitor; powers VCC-side circuitry and defines output swing |
| EN | Enable control input | Pull low to disable VCC-side outputs (three-state) and activate 6kΩ VL-side pulldowns |
| GND | Ground reference | Common return for both supply domains; must connect to exposed pad (EP) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0108RKL | 8-channel auto-directional translator with 32mA drive strength; requires no enable pin; 1.2V–3.6V I/O range; no ±15kV ESD rating | Preferred for high-drive digital buses (e.g., I²C with long traces); unsuitable for ESD-critical hot-plug interfaces | Select TXB0108RKL when driving capacitive loads >30pF or when direction detection must be fully autonomous |
| SN74AVC8T245RHLR | 8-bit unidirectional translator with separate A/B direction control; 1.2V–3.6V; 24mA drive; no integrated ESD protection | Used where strict unidirectional flow is required (e.g., address/data separation); mandates external ESD protection | Choose SN74AVC8T245RHLR for cost-sensitive industrial control where layout allows discrete ESD components |

FAQ
What is the maximum data rate supported by the MAX3002EBP?
The MAX3002EBP guarantees 20Mbps operation across its full specified voltage range (+1.2V ≤ VL ≤ VCC ≤ +5.5V). Under optimized conditions - specifically +1.8V ≤ VL ≤ VCC ≤ +2.5V with 15pF load - it achieves up to 35Mbps. This performance is validated per the Timing Characteristics table in the official MAX3002EBP datasheet, with propagation delay capped at 15ns in both directions.
Does the MAX3002EBP require a direction-control signal?
No, the MAX3002EBP does not require a direction-control signal. It uses a proprietary bidirectional architecture that automatically detects signal flow on each of its eight channels, enabling seamless translation from VL to VCC or VCC to VL without external DIR pin management. This eliminates firmware overhead and PCB routing for direction logic - a key differentiator versus unidirectional translators like the SN74AVC8T245RHLR.
What package type is used for the MAX3002EBP?
The MAX3002EBP is supplied in a 20-bump UCSP (Ultra Compact Silicon Package) measuring 2.5mm × 2.5mm with 0.5mm pitch and an exposed thermal pad. This package matches the pinout of the 20-pin TSSOP variant (e.g., MAX3002EUP) for layout reuse, while delivering superior board-area efficiency essential for compact portable designs.
How does the EN pin function on the MAX3002EBP?
On the MAX3002EBP, the EN pin is an active-low enable input. When pulled low, it places all eight I/O VCC pins into high-impedance three-state while activating internal 6kΩ pulldown resistors on all eight I/O VL pins. Driving EN high (to VL) restores normal bidirectional operation. This feature enables power-gating of the high-voltage domain while maintaining defined logic states on the low-voltage side.
Is the MAX3002EBP compatible with 1.2V logic systems?
Yes, the MAX3002EBP explicitly supports VL down to +1.2V, making it compatible with modern ultra-low-power processors, FPGAs, and memory interfaces operating at 1.2V core voltage. Its input thresholds scale with VL (VIHL = 2/3×VL, VILL = 1/3×VL), ensuring reliable switching and >300mV noise margin even at 1.2V - confirmed in the Electrical Characteristics table of the MAX3002EBP datasheet.
