Analog Devices Inc./Maxim Integrated MAX13013EXT+T

Overview

MAX13013EXT+T from Maxim Integrated is a single-channel bidirectional logic-level translator IC designed for high-speed voltage translation between 1.2V–3.6V domains in multivoltage systems. It supports guaranteed 100Mbps data transfer when VL ≥ 1.8V, features active-high EN control, operates from –40°C to +85°C, and delivers ultra-low 0.03µA VCC supply current in tri-state mode. It enables SPI/MICROWIRE interface bridging between low-voltage ASICs and higher-voltage peripherals.

For engineers reviewing the MAX13013EXT+T datasheet, MAX13013EXT+T pinout, MAX13013EXT+T application, or MAX13013EXT+T equivalent, this page provides verified electrical specifications, SC70-6 package details, bidirectional timing behavior (tPLH/tPHL ≤ 6.5ns), enable-controlled tri-state operation, and validated alternatives for level-shifting designs requiring sub-10ns propagation and <0.1µA quiescent current.

Technical Context

The MAX13013EXT+T implements a one-shot accelerator output architecture that activates only during signal transitions on either I/O VL_ or I/O VCC_, minimizing static power while enabling fast edge rates. Its dual-rail design accepts independent VL (+1.2V to VCC − 0.4V) and VCC (+1.65V to +3.6V) supplies, with input thresholds set at 1/3 and 2/3 of each rail voltage.

It supports true bidirectional translation without inversion on a single data line, with matched 12.5Ω (VL-side) and 18.5Ω (VCC-side) output impedances ensuring controlled rise/fall times ≤ 4ns into 40pF loads. The EN input directly references VL and places all I/Os in high-impedance state when low, reducing VCC current to 0.03µA and VL current to 0.1µA.

Key Specifications

Pinout & Package

FAQ

What is the minimum VL voltage supported by MAX13013EXT+T?

MAX13013EXT+T supports VL as low as +1.2V, though guaranteed 100Mbps operation requires VL ≥ +1.8V. At VL = +1.2V, the device maintains functionality at 80Mbps with full electrical compliance across the –40°C to +85°C range. The VL supply must remain ≤ VCC − 0.4V during normal operation, but transient VL > VCC during power-up is safe and non-damaging.

Does MAX13013EXT+T require external pull-up resistors on its I/O lines?

No, MAX13013EXT+T does not require external pull-up resistors. It integrates internal pull-up (120Ω on I/O VL_, 2.5kΩ on I/O VCC_) and pulldown (75Ω on I/O VL_, 2.5kΩ on I/O VCC_) resistors to establish defined logic states during tri-state or floating conditions. External resistors may degrade timing performance and are unnecessary unless specific bus topology requirements dictate otherwise.

Can MAX13013EXT+T translate I²C signals?

MAX13013EXT+T is not recommended for I²C level translation. Its architecture lacks open-drain compatibility and does not support the bidirectional, wired-AND behavior required by I²C buses. For I²C, Maxim specifies dedicated solutions such as the MAX3372E–MAX3379E family. Using MAX13013EXT+T on I²C lines risks bus contention, signal corruption, and failure to meet I²C timing specifications.

What is the propagation delay mismatch between VL→VCC and VCC→VL directions in MAX13013EXT+T?

The propagation delay mismatch (skew) between I/O VL_ → I/O VCC_ (6.5ns) and I/O VCC_ → I/O VL_ (6ns) is 0.5ns under typical conditions (CIO = 15pF, VCC = 2.5V, VL = 1.8V). The datasheet guarantees part-to-part skew ≤ 4ns across temperature and voltage, ensuring deterministic timing alignment in synchronous protocols like SPI where clock and data edges must remain correlated.

How does the enable (EN) pin behave during power-up sequencing of MAX13013EXT+T?

The EN pin of MAX13013EXT+T is referenced to VL and is active-high. During power-up, if VL rises before VCC, EN remains invalid until VL reaches ~0.6V (1/3 × VL threshold), after which the device enters functional state once EN is driven high. If EN is left floating, it defaults to low due to lack of internal pull-up, keeping the device in tri-state - a fail-safe behavior that prevents spurious outputs during supply ramp-up.
