PI6ULS5V9515AUEX

Signal Buffers, Repeaters, Splitters Overview

The PI6ULS5V9515AUEX is a single-channel I2C bus and SMBus repeater manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.3 V to 3.6 V and supports data rates up to 400 kHz. The device features an active HIGH enable input (EN) that controls signal pass-through between Port 0 and Port 1. When enabled, SCL0 mirrors SCL1 and SDA0 mirrors SDA1; when disabled, the ports are isolated. It utilizes an MSOP-8 package with four functional pins: GND, EN, SDA0/SDA1, and SCL0/SCL1.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides bidirectional signal buffering for I2C and SMBus protocols
• Features a single active HIGH enable pin for port control
• Supports low-voltage operation from 2.3 V to 3.6 V
• Includes built-in contention handling for LOW-level inputs

Signal Buffers, Repeaters, Splitters Applications

• Extending I2C bus distance in embedded systems
• Isolating multiple I2C segments on a single board
• Level translation between different voltage domains
• Signal buffering for high-capacitance I2C loads

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'UEX' corresponds to the MSOP-8 tape and reel packaging configuration. Confirm RoHS 3 compliance status through official manufacturer documentation prior to procurement. Ensure the component matches the required voltage and speed specifications for the target application.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for applications requiring a single-channel I2C repeater with minimal pin count. The MSOP-8 package offers a compact footprint suitable for space-constrained designs. Verify that the system voltage remains within the 2.3 V to 3.6 V operating range to ensure proper functionality.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI6ULS5V9515A series of I2C/SMBus repeaters. The 'U' suffix indicates the MSOP-8 package variant, while 'EX' denotes tape and reel packaging. It is functionally equivalent to the PI6ULS9515A but packaged specifically for surface-mount assembly in consumer electronics.

Signal Buffers, Repeaters, Splitters FAQ

How does the Enable (EN) pin affect the signal path?

When the EN pin is HIGH, signals pass directly from Port 0 to Port 1. When LOW, the repeater is disabled and isolates the two ports.

What is the maximum supported data rate?

The device supports standard mode I2C speeds up to 400 kHz.

Does the device support level shifting?

Yes, it can buffer signals between different voltage levels within its specified operating range, acting as a level translator.
