PCA9515ADT

Signal Buffers, Repeaters, Splitters Overview

The PCA9515ADT is a dual bidirectional I2C bus and SMBus repeater manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and supports clock frequencies up to 400 kHz. The device features a propagation delay of 45 ns and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in an 8-pin SOIC (VSSOP-8) format, it serves as a signal buffer and repeater for interface applications.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides dual bidirectional signal buffering for I2C and SMBus protocols
• Supports high-speed communication with a maximum clock frequency of 400 kHz
• Operates within a wide industrial temperature range suitable for demanding environments

Signal Buffers, Repeaters, Splitters Applications

• Extending I2C bus distance in embedded systems
• Isolating bus segments to prevent fault propagation
• Signal buffering in SMBus compatible networks

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'DT' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage levels between 2.3 V and 3.6 V. Cross-reference with NXP documentation if sourcing from alternative distributors, as part numbers may vary slightly between manufacturers.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when dual-channel isolation or signal regeneration is required for I2C/SMBus buses. Confirm that the operating environment stays within the specified -40°C to +85°C range. Verify that the system power supply does not exceed the maximum rating of 3.6 V to ensure reliable operation without external level shifting.

Signal Buffers, Repeaters, Splitters Part Context

This device belongs to the PCA9515 family of bus repeaters, designed to enhance signal integrity and extend bus reach. It is functionally similar to the PCA9515BDGKR but differs in packaging and specific electrical characteristics. The ADT variant typically denotes a specific tape-and-reel configuration for automated assembly.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PCA9515BDGKR is a documented alternative within the same product family. Verify pinout compatibility and package dimensions before substitution. Other potential replacements include the PCA9515B series, though electrical parameters must be compared against the original design requirements.
