PCA9515ADGKTG4

Signal Buffers, Repeaters, Splitters Overview

The PCA9515ADGKTG4 is a dual bidirectional I2C bus and SMBus repeater manufactured by Texas Instruments. It operates within a supply voltage range of 2.3V to 3.6V and supports data rates up to 400kHz. The device features two independent channels, each capable of buffering signals between master and slave devices. It functions reliably across an operating temperature range of -40°C to +85°C. The component is housed in an 8-TSSOP package with dimensions of 3.00mm width.

Signal Buffers, Repeaters, Splitters Feature Summary

• Provides bidirectional signal translation for I2C and SMBus protocols
• Isolates bus capacitance to support extended trace lengths
• Supports hot insertion without causing bus contention

Signal Buffers, Repeaters, Splitters Applications

• Extending I2C bus distance in embedded systems
• Buffering high capacitance loads on SMBus networks
• Connecting multiple I2C slaves to a single controller

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'TG4' against official Texas Instruments documentation to confirm lead-free status and RoHS compliance. Ensure the tape and reel packaging matches system assembly requirements. Cross-reference the full part number with the manufacturer's current lifecycle status to avoid obsolescence risks during production.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when dual-channel isolation is required for I2C or SMBus applications. Verify that the 2.3V to 3.6V supply voltage aligns with the target system logic levels. Confirm that the 8-TSSOP package fits the available PCB footprint and thermal constraints.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PCA9515 family of bus repeaters. It serves as a buffer to overcome capacitance limitations inherent in standard I2C designs. The device enables communication between masters and slaves separated by significant board traces or cable connections.
