MAX3391EETD+

Translators, Level Shifters Overview

The MAX3391EETD+ is a quad, unidirectional low-voltage level translator from the MAX3372E–MAX3393E family. It operates with VCC supply voltages ranging from +1.65V to +5.5V and VL supply voltages from +1.2V to +5.5V. The device supports data rates up to 8Mbps across the full voltage range, reaching 10Mbps when operating between +1.2V and +3.3V, and 16Mbps within specific domains of +1.8V to +2.5V or +2.5V to +3.3V. It features ±15kV ESD protection on the VCC side, thermal short-circuit protection, and a three-state output mode that reduces supply current to less than 1μA.

Translators, Level Shifters Procurement Notes

Verify the exact package type against the datasheet pinout diagrams, as the 'EETD+' suffix indicates a specific TDFN variant within the MAX339x family. Confirm the directional configuration matches system requirements, as this model provides unidirectional translation. Ensure supply sequencing complies with the specified voltage limits to prevent latch-up during power-up.

Translators, Level Shifters Selection Notes

Select this component for applications requiring robust ESD protection on external interfaces combined with low-power standby capabilities. The unidirectional nature simplifies design for fixed-direction data buses like SPI or I2C. Consider the specific voltage domains required for maximum data rates when choosing between the 8Mbps and 16Mbps operational modes based on the target system architecture.
