Analog Devices Inc./Maxim Integrated MAX13032EETE+

Overview

MAX13032EETE+ from Maxim Integrated is a 6-channel bidirectional logic-level translator IC designed for high-speed voltage translation between VL = +1.62V to +3.2V and VCC = +2.2V to +3.6V domains. It supports 100Mbps data transfer, features automatic shutdown when VCC < VL, and maintains high-impedance I/O VL_ and 16.5kΩ-to-GND I/O VCC_ states during shutdown. It is used in SD/MiniSD/MMC memory card interfaces where low-voltage ASICs interface with 3.3V host controllers.

For engineers reviewing the MAX13032EETE+ datasheet, MAX13032EETE+ pinout, MAX13032EETE+ application, or MAX13032EETE+ equivalent, key selection considerations include its guaranteed 100Mbps operation with 4mA input drivers, ±15kV HBM ESD protection on VCC-side I/Os, 6ns propagation delay (tPVL-VCC), tri-state leakage <2µA in shutdown, and compatibility with both push-pull and open-drain signaling without external pullups.

Technical Context

The MAX13032EETE+ implements bidirectional level translation using nMOS pass gates with integrated rise/fall time accelerator stages that activate only during signal transitions-reducing static power while enabling sub-3ns edge acceleration. Its architecture includes internal 30µA current-source pullups on all I/O lines, eliminating need for external resistors and supporting direct connection to open-drain drivers.

Unlike MAX13030E–MAX13034E variants, MAX13032EETE+ lacks an EN pin and relies solely on automatic shutdown triggered by VCC < VL. During shutdown, it asserts high-impedance on all I/O VL_ pins and pulls I/O VCC_ to GND via 10–23kΩ internal pulldown resistors-ensuring defined low-state behavior for downstream 3.3V receivers when the 1.8V domain remains active.

Key Specifications

Pinout & Package

MAX13032EETE+ is packaged in a 16-pin TQFN-EP (4mm × 4mm) with exposed paddle (EP) requiring connection to GND for thermal and ESD performance. Pin numbering follows standard top-view layout with pin 1 at top-left corner.

Manufacturer

Maxim Integrated (now part of Analog Devices) is a semiconductor company specializing in high-performance analog and mixed-signal ICs for power, sensing, connectivity, and interface applications.

The MAX13030E–MAX13035E family was designed specifically for high-speed, low-power bidirectional level translation in memory-card interfaces-addressing the need for compact, ESD-hardened, multi-channel solutions in space-constrained portable electronics.

FAQ

What is the shutdown trigger condition for MAX13032EETE+?

MAX13032EETE+ enters automatic shutdown when VCC falls below VL by more than 0.2V-no external enable signal is required. During shutdown, all I/O VL_ pins go high-impedance, and I/O VCC_ pins are actively pulled to GND via internal 10–23kΩ resistors. This behavior is confirmed in the Ordering Information table and Electrical Characteristics section of the MAX13030E–MAX13035E datasheet.

Does MAX13032EETE+ support open-drain drivers on the VL side?

Yes, MAX13032EETE+ supports open-drain drivers on both VL and VCC sides due to its internal 30µA current-source pullups on all I/O lines. This eliminates the need for external pullup resistors and ensures clean signal rise times-even with capacitive loads up to 15pF on VL-side lines. The device's architecture is explicitly validated for open-drain operation in the Application Information section.

What package type and thermal characteristics does MAX13032EETE+ have?

MAX13032EETE+ uses a 16-pin TQFN-EP package (4mm × 4mm) with exposed paddle. Its thermal resistance is θJA = 40°C/W and θJC = 6°C/W on a multilayer board per JEDEC JESD51-7. The exposed paddle must be soldered to a GND plane to achieve rated power dissipation (2000mW at +70°C) and ensure ESD robustness-details are specified in the Package Information section.

Can MAX13032EETE+ be used for I²C level translation?

No, MAX13032EETE+ is not recommended for I²C level translation. Its architecture relies on active acceleration pulses and internal current-source pullups incompatible with I²C's bidirectional open-drain bus topology and strict rise-time requirements. The datasheet explicitly directs users to MAX3372E–MAX3379E or MAX3390E–MAX3393E families for I²C applications.

What is the maximum capacitive load MAX13032EETE+ can drive on I/O VCC_ lines?

MAX13032EETE+ is characterized to drive up to 10pF on I/O VCC_ lines while maintaining 2.5ns rise/fall times and 6.5ns propagation delay. Driving loads beyond 10pF increases transition time and propagation delay-e.g., at 25pF, tRVCC/tFVCC degrades to ~3.5ns and tPVL-VCC exceeds 8ns. Layout best practices recommend minimizing trace length and avoiding stubs to stay within this limit.
