PI4ULS3V204LEX

Translators, Level Shifters Overview

The PI4ULS3V204LEX is a 4-bit bidirectional voltage level translator manufactured by Diodes Incorporated in a 14-pin TSSOP package. It supports dual supply rails VCCA and VCCB ranging from 1.1V to 3.6V. The device provides data rates up to 24 Mb/s for push-pull applications and 2 Mb/s for open-drain configurations. Propagation delay ranges from 3 ns to 260 ns depending on the driving configuration, with an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Auto-sensing architecture eliminates the need for a directional control pin
• Integrated 10 kΩ pull-up resistors support open-drain bus applications
• Non-preferential power-up sequencing prevents damage during power transitions
• High ESD protection rating exceeding 8000V HBM

Translators, Level Shifters Applications

• I2C communication buses
• SMBus interfaces
• MDIO protocols
• Low voltage ASIC level translation

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'LEX' corresponds to the 14-pin TSSOP tape and reel packaging format. Confirm RoHS compliance and lead-free status requirements against project specifications. Ensure the selected component matches the required operating temperature range and voltage levels for the target application design.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring automatic bidirectional translation between two independent logic domains without manual direction control. It is suitable for mixed-voltage environments where supply rails differ but remain within the 1.1V to 3.6V operational window. Consider the integrated pull-ups for simplified open-drain circuit designs.

Translators, Level Shifters Part Context

This part belongs to the PI4ULS3V204 family of auto-sensing translators. Other variants include the ZBEX (TQFN) and GAEX (CSP) packages. All share identical electrical characteristics and functionality, differing only in physical footprint and mounting style for PCB layout optimization.

Translators, Level Shifters Replacement Considerations

Direct replacements include PI4ULS3V204ZBEX and PI4ULS3V204GAEX. These parts maintain functional equivalence while offering alternative package types such as TQFN or CSP for space-constrained layouts.
