MAX14842ATE+T

Translators, Level Shifters Overview

The MAX14842ATE+T is a 6-channel digital ground-level translator in a 16-pin TQFN package. It translates signals between domains with up to 72V ground difference. It includes four unidirectional channels supporting 30Mbps and two bidirectional channels supporting 2Mbps. Bidirectional channels feature open-drain outputs for I2C compatibility. Supply voltages VDDA and VDDB range from 3.0V to 5.5V relative to their respective grounds. The device operates over an automotive temperature range of -40°C to +125°C.

Translators, Level Shifters Feature Summary

Translators, Level Shifters Procurement Notes

Verify the component matches the specific ATE suffix for the -40°C to +125°C automotive temperature range. Confirm the package type is the 16-pin TQFN with exposed pad. Ensure the datasheet revision aligns with current specifications. Check that the ordering information explicitly lists the MAX14842ATE+T variant. Validate RoHS compliance status through official manufacturer documentation.

Translators, Level Shifters Selection Notes

Select this device when translating logic levels between circuits with significant ground offsets up to 72V. Use the unidirectional channels for standard push-pull signal transmission at speeds up to 30Mbps. Utilize the bidirectional channels for I2C applications requiring clock stretching support. Ensure supply voltages are within the 3.0V to 5.5V range for both sides.

Translators, Level Shifters Part Context

The MAX14842 belongs to Maxim Integrated's family of digital level translators designed for systems with isolated or offset ground references. It combines ground shifting with logic level translation in a single compact package. The device supports simultaneous operation of unidirectional and bidirectional channels without requiring direction control inputs.
