MAX14591EWA+T

Translators, Level Shifters Overview

The MAX14591EWA+T is a dual-channel, bidirectional logic-level translator designed for multivoltage systems. It operates with VCC from +1.65V to +5.5V and VL from +0.9V to min(VCC + 0.3V, +3.6V). The device supports push-pull operation up to 8MHz and open-drain operation above 4MHz. It features a three-state input (TS) for shutdown control, internal pullup resistors, and thermal shutdown protection at +150°C. The component is specified over an extended temperature range of -40°C to +85°C and utilizes an 8-bump WLP package.

Translators, Level Shifters Feature Summary

• Bidirectional level translation between low-voltage VL and high-voltage VCC domains
• Optimized for I2C and MDIO bus applications with high-speed open-drain capability
• Three-state input enables shutdown mode with high-impedance outputs
• Internal pullup resistors activate automatically when corresponding power supply is present

Translators, Level Shifters Applications

• Devices with I2C Communication
• Devices with MDIO Communication
• General Logic-Level Translation

Translators, Level Shifters Procurement Notes

Verify the specific suffix EWA+T corresponds to the 8-bump WLP package configuration. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the ordering information matches the required lead-free specifications. Cross-reference the datasheet revision date to confirm current manufacturing parameters. Validate that the component meets the required environmental operating conditions.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits with different voltage domains, specifically where VL can operate as low as 0.9V. Choose this device for designs requiring high-speed data transfer on I2C or MDIO buses. Consider the WLP package for space-constrained layouts. Ensure the system controller supports the necessary three-state control signals for power management.

Translators, Level Shifters Part Context

This part belongs to the MAX14591 series of logic-level translators manufactured by Analog Devices / Maxim Integrated. It is distinct from other Maxim ICs by its specific focus on bidirectional translation with integrated pullups. The WLP variant offers a compact footprint compared to TDFN options. It serves as a bridge for mixed-voltage digital communication protocols.
