MAX14842ATE+

Translators, Level Shifters Overview

The MAX14842ATE+ is a six-channel digital ground-level translator manufactured by Analog Devices Inc./Maxim Integrated. It translates signals between domains with different ground references up to 72V. The device includes four unidirectional channels supporting data rates up to 30Mbps and two bidirectional channels supporting up to 2Mbps. It operates on supply voltages from +3.0V to +5.5V, features undervoltage lockout, and is specified over the -40°C to +125°C automotive temperature range in a 16-pin TQFN package.

Translators, Level Shifters Feature Summary

• Translates digital signals between domains with ground differences up to 72V
• Supports I2C clock stretching and hot swapping on bidirectional channels
• Features push-pull outputs for unidirectional channels and open-drain outputs for bidirectional channels
• Includes undervoltage lockout for defined behavior during power-up and transients

Translators, Level Shifters Applications

• Telecommunication Systems
• Battery Management
• I2C, SMBus, SPI, and MICROWIRE Signals
• Medical Systems
• Power-Over-Ethernet

Translators, Level Shifters Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications. Ensure that the ground potential difference between domains does not exceed the 72V limit. Check for RoHS compliance status indicated by the '+' suffix. Confirm availability through authorized distributors as supply conditions may vary.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic circuits across isolated or offset ground planes exceeding standard voltage levels. It is suitable for applications requiring simultaneous unidirectional and bidirectional translation without direction control inputs. Consider the 30Mbps rate for high-speed unidirectional links and the 2Mbps rate for I2C-compatible bidirectional buses.

Translators, Level Shifters Part Context

This part belongs to the MAX14842 family of digital translators. It provides both ground-level shifting and logic-level translation. The ATE+ suffix indicates an automotive-grade version in a 16-pin TQFN-EP package with lead-free/RoHS-compliant packaging. It replaces older versions like the MAX14842ETE+ which has been removed from the ordering information.
