MAX3379EETD+

Translators, Level Shifters Overview

The MAX3379EETD+ is a unidirectional voltage level translator from the MAX3372E–MAX3379E family, manufactured by Analog Devices Inc./Maxim Integrated. 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 operating range, reaching 10Mbps within specific voltage domains (+1.2V ≤ VL ≤ VCC ≤ +3.3V) and 16Mbps at lower voltages (+1.8V ≤ VL ≤ VCC ≤ +2.5V). It features ±15kV ESD protection on I/O VCC lines, thermal short-circuit protection, and a three-state output mode reducing supply current to less than 1μA.

Translators, Level Shifters Feature Summary

• Unidirectional level shifting between low-voltage logic systems and higher-voltage systems
• Integrated ±15kV ESD protection on I/O VCC lines for external signal routing
• Three-state output mode enabling multidrop network applications with ultra-low quiescent current
• Thermal short-circuit protection that automatically forces outputs to high-impedance during fault conditions

Translators, Level Shifters Applications

• SPI, MICROWIRE, and I2C Level Translation
• Low-Voltage ASIC Level Translation
• Smart Card Readers
• Cell-Phone Cradles
• Portable POS Systems

Translators, Level Shifters Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and ensure the component meets environmental standards required for your specific application. Check for any recent lifecycle changes or obsolescence notices directly from Analog Devices before finalizing procurement plans.

Translators, Level Shifters Selection Notes

Select this component when interfacing low-voltage ASICs or PLDs with higher-voltage systems requiring unidirectional data transfer. Ensure the design accommodates the specified voltage ranges for VCC and VL. Consider the package availability in 14-pin TSSOP or TDFN formats based on board space constraints. Verify that the load capacitance and driver impedance align with the desired maximum data rate specifications.

Translators, Level Shifters Part Context

This part belongs to the MAX3372E–MAX3379E series of ±15kV ESD-protected level translators. These devices are designed to facilitate data transfer in multivoltage systems by translating signals between different logic levels. The family includes both unidirectional and bidirectional variants, with the MAX3379E specifically providing four channels of unidirectional translation suitable for serial interface protocols.

Translators, Level Shifters Replacement Considerations

The MAX3379EEUD is a quad level shifter available in a 14-TSSOP package with similar electrical characteristics.
