MAX3377EETD+T

Translators, Level Shifters Overview

The MAX3377EETD+T is a quad bidirectional level translator from the MAX3372E–MAX3379E family. It operates with VCC supply voltages ranging from +1.65V to +5.5V and VL logic levels from +1.2V to +5.5V. The device provides ±15kV ESD protection on I/O VCC lines and features thermal short-circuit protection. It supports data rates up to 8Mbps across the full voltage range, with higher speeds achievable in specific domains. The part utilizes a transmission-gate design for bidirectional translation and includes a three-state output mode that reduces supply current to less than 1μA.

Translators, Level Shifters Feature Summary

• Bidirectional level translation between low-voltage ASICs/PLDs and higher voltage systems
• Three-state output mode enabling multidrop network operation with ultra-low standby current
• Robust ±15kV ESD protection on I/O VCC lines compliant with Human Body Model standards
• Thermal short-circuit protection automatically forces the device into three-state mode during fault conditions

• 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 suffix 'ETD' against official manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure ordering specifications match the required pin configuration and electrical characteristics for your specific multivoltage system interface.

Translators, Level Shifters Selection Notes

Select this component when interfacing between disparate voltage domains requiring bidirectional data transfer. The quad configuration suits applications needing multiple simultaneous signal translations. Consider the guaranteed 8Mbps data rate for standard serial interfaces. Evaluate the three-state capability if bus contention management is required. Verify that the operating voltage ranges of both connected systems fall within the specified VCC and VL limits.

Translators, Level Shifters Part Context

This device belongs to the MAX3372E–MAX3379E series of ESD-protected level translators. These components are designed to facilitate data transfer in multivoltage systems by shifting logic levels between different supply rails. The family includes both dual and quad variants with varying data rate capabilities. The MAX3377E specifically offers four independent bidirectional channels in a compact surface-mount package suitable for space-constrained portable electronics.

Translators, Level Shifters Replacement Considerations

Direct substitutes within the same family include MAX3378E and MAX3379E, though these may offer unidirectional functionality instead of bidirectional translation. Verify pin compatibility and package dimensions before substitution. Other family members like MAX3372E provide similar protection but differ in channel count and maximum data rate specifications.
