Analog Devices Inc./Maxim Integrated MAX13032EEBE+

Overview

The MAX13032EEBE+ from Maxim Integrated is a 6-channel bidirectional logic-level translator IC designed for high-speed voltage translation between +1.62V–+3.2V (VL) and +2.2V–+3.6V (VCC) domains. It supports guaranteed 100Mbps data transfer, features six I/O pairs with internal 30µA pull-up current sources, and operates across –40°C to +85°C in SD/MiniSD/MMC memory-card interface applications.

For engineers reviewing the MAX13032EEBE+ datasheet, MAX13032EEBE+ pinout, MAX13032EEBE+ application, or MAX13032EEBE+ equivalent, key selection criteria include its UCSP-16 (2mm × 2mm) package, shutdown behavior (I/O VL_ high-impedance / I/O VCC_ pulled to GND), ±15kV ESD protection on VCC-side I/Os, and compatibility with 4mA minimum external drivers.

Technical Context

The MAX13032EEBE+ implements nMOS pass-gate architecture with output-accelerator stages that generate short pulses during signal transitions to actively charge/discharge load capacitance-enabling fast rise/fall times (≤2.5ns) without external pull-ups. Its automatic shutdown activates when VCC < VL, and it accepts open-drain or push-pull inputs.

Unlike MAX13030E–MAX13034E variants, the MAX13032EEBE+ lacks an EN pin and relies solely on automatic shutdown; its I/O VCC_ pins are internally pulled to GND during shutdown (16.5kΩ), while I/O VL_ pins remain high-impedance-making it suitable for systems where controlled low-state termination on the VCC side is required during power sequencing.

Key Specifications

Pinout & Package

MAX13032EEBE+ uses a 16-bump wafer-level chip-scale package (UCSP), 2mm × 2mm, with exposed paddle connected to GND. Pin mapping follows standard UCSP bump grid (A1–D4).

FAQ

What is the shutdown behavior of the MAX13032EEBE+?

The MAX13032EEBE+ enters automatic shutdown when VCC falls below VL. During shutdown, all I/O VL_ pins enter high-impedance state, while all I/O VCC_ pins are actively pulled to GND via 16.5kΩ internal resistors. This behavior is fixed per the MAX13032E variant and does not require an external EN signal-ensuring predictable termination during asymmetric power sequencing in memory-card systems.

Does the MAX13032EEBE+ require external pull-up resistors?

No, the MAX13032EEBE+ does not require external pull-up resistors. It integrates internal 30µA current-source pull-ups on all I/O lines, enabling direct interface with open-drain or weak push-pull drivers. External pull-ups are discouraged as they conflict with the internal accelerator architecture and may degrade rise/fall time performance or cause contention during transitions.

What package type is used by the MAX13032EEBE+?

The MAX13032EEBE+ uses a 16-bump UCSP (Ultra-Compact Silicon Package), measuring 2mm × 2mm with a 0.5mm pitch. The package features an exposed thermal paddle that must be soldered to GND for optimal thermal performance and ESD robustness. It is lead-free and RoHS-compliant.

Can the MAX13032EEBE+ translate clock signals?

The MAX13032EEBE+ translates general-purpose bidirectional signals-including clock lines-but does not include the CLK_RET output found in the MAX13035E variant. For clock-return functionality (where CLK_VL is echoed as CLK_RET referenced to VL), the MAX13035EEBE+ must be selected instead. MAX13032EEBE+ handles CLK_VL/CLK_VCC translation like any other I/O pair.

What is the maximum capacitive load the MAX13032EEBE+ can drive?

The MAX13032EEBE+ is characterized for loads up to 40pF on I/O VCC_ and 15pF on I/O VL_ under typical conditions (VCC = 3.3V, VL = 1.8V). Rise/fall times remain ≤2.5ns at 10pF, but increase to ~300ps–400ps at 40pF. For reliable 100Mbps operation, total trace + pin capacitance should be kept ≤15pF on VL-side and ≤10pF on VCC-side to maintain timing margins.
