PI4ULS3V16AEX

Translators, Level Shifters Overview

The PI4ULS3V16AEX is a 16-bit universal bidirectional level shifter with automatic direction control, manufactured by Diodes Incorporated. It operates on dual supply rails (VCCA and VCCB) ranging from 1.2V to 3.6V. The device supports bus speeds up to 180 Mbps for push-pull applications and provides a drive capability of 12mA. It features independent translation for each bit, ensuring asynchronous communication between data buses without explicit direction control signals. The component is housed in a 56-contact plastic TQFN package.

Translators, Level Shifters Feature Summary

• Automatic direction control enables seamless bidirectional data translation between A and B ports without external direction management.
• Supports fast bus speeds up to 180 Mbps for push-pull applications while maintaining low quiescent current.
• Provides robust ESD protection exceeding JESD22 standards, including -2000V Human Body Model performance.

Translators, Level Shifters Applications

• Voltage Translation
• Bus Relay

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and lead-free status. Ensure compatibility with the required 56-pin TQFN footprint during PCB layout. Confirm that the voltage levels on both VCCA and VCCB rails remain within the specified 1.2V to 3.6V range for reliable operation.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems requiring 16-bit parallel data translation across varying voltage domains. It is suitable for applications needing high-speed asynchronous communication without complex control logic. Consider the 56-pin TQFN package constraints and ensure adequate thermal management for the operating environment.

Translators, Level Shifters Part Context

This part belongs to the PI4ULS3V series of universal bidirectional level shifters. It is designed for low-voltage digital interfaces where multiple data lines require simultaneous translation. The device integrates automatic direction sensing, simplifying system design compared to manually controlled translators.

Translators, Level Shifters Replacement Considerations

Check datasheets for alternative 16-bit level shifters with similar voltage ranges and pin counts. Verify if substitute parts offer compatible automatic direction control and comparable ESD protection ratings.
