PI4ULS3V204ZBEX

Translators, Level Shifters Overview

The PI4ULS3V204ZBEX is a 4-bit bidirectional voltage level translator manufactured by Diodes Incorporated in a 14-pin TQFN package. It supports supply voltages from 1.1V to 3.6V on both ports. The device provides data rates up to 24 Mbps for push-pull applications and 2 Mbps for open-drain configurations. Propagation delays range from 3 ns to 260 ns depending on the driving configuration. It features integrated 10 kΩ pull-up resistors, low bit-to-bit skew of 1 ns, and ESD protection exceeding 8000V HBM.

Translators, Level Shifters Feature Summary

• Auto-sensing architecture eliminates the need for directional control signals
• Integrated 10 kΩ pull-up resistors support open-drain bus applications
• Non-preferential power-up sequencing ensures safe operation during power transitions
• Low bit-to-bit skew maintains signal integrity across multiple channels

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the ZB suffix confirms the 14-pin 3.5x3.5 mm TQFN package variant. Confirm RoHS compliance and lead-free status as specified in the ordering information. Ensure the datasheet revision matches current design requirements. Check for specific automotive qualification needs if applicable to the target application environment.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring bidirectional translation between dual supply rails within the 1.1V to 3.6V range. It is suitable for applications needing auto-direction sensing without external control pins. Consider the 24 Mbps maximum data rate for high-speed push-pull signaling or the 2 Mbps limit for open-drain implementations like I2C buses.

Translators, Level Shifters Part Context

This part belongs to the PI4ULS3V204 family of configurable dual-supply translators. Other variants include the L package (TSSOP-14) and GA package (CSP-12). All share identical electrical characteristics but differ in physical footprint and pinout mapping. The ZB suffix specifically denotes the thin quad flat no-lead form factor.

Translators, Level Shifters Replacement Considerations

Direct substitutes within the same family include PI4ULS3V204LEX and PI4ULS3V204GAEX. Verify package compatibility before substitution. Cross-family replacements require validation of pinouts and electrical parameters against the original design specifications.
