MAX9421EHJ

Translators, Level Shifters Overview

The MAX9421EHJ is a high-speed, low-power, quad bidirectional translating level shifter manufactured by Analog Devices Inc. (formerly Maxim Integrated). Designed for mixed-voltage systems, it facilitates signal translation between different logic voltage domains without requiring direction control pins. The device supports simultaneous bidirectional data transfer across four channels, making it suitable for interfacing components operating at varying supply voltages in compact electronic designs.

Translators, Level Shifters Feature Summary

• Provides bidirectional voltage translation for digital signals between disparate logic families
• Operates without external direction control pins, enabling automatic signal routing
• Supports multiple independent voltage domains for flexible system integration

Translators, Level Shifters Applications

• Interfacing microcontrollers with lower voltage peripherals
• Level shifting between I2C and SPI bus standards
• Mixed-signal circuit board design requiring voltage domain isolation

Translators, Level Shifters Procurement Notes

Verify the specific suffix EHJ to confirm package type and temperature range. Confirm current availability status as legacy Maxim products may have limited distribution through Analog Devices channels. Ensure compatibility with your target voltage levels before procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation is required without complex control logic. It is appropriate for applications needing minimal pin count and low power consumption. Verify that the input and output voltage ranges match your system's specific logic levels.

Translators, Level Shifters Part Context

This part belongs to the MAX94xx series of level shifters from Maxim Integrated, now part of Analog Devices. These devices are widely used in portable electronics and industrial controls where space efficiency and low power are critical constraints for mixed-voltage interface solutions.

Translators, Level Shifters Replacement Considerations

Check for MAX9420 variants or other quad level shifters in the MAX94xx family. Ensure substitute parts support the same bidirectional functionality and voltage ranges.
