MAX3377EETD+

Overview

The MAX3377EETD+ is a quad bidirectional level translator from the MAX3372E–MAX3379E family, manufactured by Analog Devices Inc./Maxim Integrated. It facilitates data transfer between low-voltage ASICs/PLDs and higher voltage systems using externally applied voltages VCC (+1.65V to +5.5V) and VL (+1.2V to +5.5V). The device operates at a guaranteed data rate of 230kbps with slew-rate limiting to reduce EMI. It features ±15kV ESD protection on I/O VCC lines, thermal short-circuit protection, and a three-state output mode that reduces supply current to less than 1μA. The component is housed in a 14-pin TDFN (3mm x 3mm) package.

Feature Summary

• Bidirectional translation allows data shifting in either direction (VL ↔ VCC) utilizing a transmission-gate-based design.
• Slew-rate limiting minimizes electromagnetic interference (EMI) emissions during signal transitions.
• Three-state output mode enables high-impedance states for multidrop network applications while reducing quiescent current.

Applications

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

Procurement Notes

Verify the specific suffix 'EETD+' against official documentation to confirm the 14-pin TDFN packaging and commercial temperature range. Ensure compatibility with the required voltage domains before procurement. Confirm RoHS compliance status through the manufacturer's latest certification documents.

Selection Notes

Select this component when bidirectional translation is required for up to four independent channels. Verify that the application voltage ranges fall within the specified limits of +1.2V to +5.5V for VL and +1.65V to +5.5V for VCC. Consider the 230kbps data rate limit and the necessity for EMI reduction via slew-rate limiting.

Part Context

This part belongs to the MAX3372E–MAX3379E series of ±15kV ESD-protected level translators. These devices are designed for multivoltage system integration, bridging logic levels between different voltage domains. The MAX3377E specifically provides quad bidirectional capability, distinguishing it from unidirectional variants in the same family.

Replacement Considerations

The MAX3378E serves as a functional substitute within the same family, offering identical quad bidirectional capabilities but operating at an 8Mbps data rate. Other family members like the MAX3372E provide dual-channel configurations instead of quad.
