PI6ULS5V9515AZEEX

Signal Buffers, Repeaters, Splitters Overview

The PI6ULS5V9515AZEEX 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 utilizes an active HIGH enable input (EN) to control signal transmission between Port 0 and Port 1. When enabled, the serial clock (SCL) and serial data (SDA) lines are directly connected; when disabled, the ports are isolated. The component is housed in an 8-pin TDFN package with dimensions of 2x3 mm.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'ZE' corresponds to the 8-pin TDFN 2x3mm package configuration. Confirm that the 'E' suffix indicates lead-free and green material compliance as defined by the manufacturer's environmental standards. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and traceability.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a single-channel buffer is required for I2C or SMBus applications. Verify that the system operating voltage falls within the 2.3 V to 3.6 V range. Consider the TDFN-8L package if space-constrained PCB layouts are necessary. Ensure the design accommodates the specified propagation delays and transition times for the target data rate.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI6ULS5V9515A series of interface signal buffers and repeaters. It is functionally equivalent to other variants in the family, distinguished primarily by its packaging type. The 'U' suffix denotes the MSOP-8 package, while the 'ZE' suffix specifies the TDFN-8L package.

Signal Buffers, Repeaters, Splitters FAQ

What is the function of the EN pin?

The EN pin is an active HIGH enable input. When high, the repeater connects SCL0/SDA0 to SCL1/SDA1. When low, the ports are disabled and isolated.

What is the maximum ESD protection rating?

The device offers ESD protection rated at 4000V according to the Human Body Model (HBM).

Does the device support SMBus protocols?

Yes, the PI6ULS5V9515AZEEX is designed as an I2C Bus/SMBus Repeater and supports both protocols.
