Signal Buffers, Repeaters, Splitters datasheet and documents for PCA9515AD/G-T

PCA9515AD/G-T

Signal Buffers, Repeaters, Splitters Overview

The PCA9515AD/G-T is a CMOS integrated circuit designed for I2C-bus and SMBus systems. It functions as a dual bidirectional buffer, extending bus capacitance limits to accommodate two buses of 400 pF each. The device supports Standard-mode and Fast-mode operations with clock frequencies up to 400 kHz. It operates within a supply voltage range of 2.3 V to 3.6 V and features 5.5 V tolerant I/O pins. Packaged in an SOIC-8 (SO8) format, it provides lock-up free operation and supports arbitration across the repeater.

Signal Buffers, Repeaters, Splitters Feature Summary

Dual-channel bidirectional buffering for I2C and SMBus extension
Lock-up free operation with static offset design
Supports arbitration and clock stretching across the repeater
5.5 V tolerant inputs with powered-off high-impedance state

Signal Buffers, Repeaters, Splitters Applications

Extending I2C bus length beyond standard capacitance limits
Isolating a 5 V bus from a 3.3 V bus
Running separate 100 kHz and 400 kHz buses simultaneously

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the package type matches the required PCB footprint, specifically the SOIC-8 variant. Confirm the operating temperature range meets system requirements, as this component is rated for -40 °C to +85 °C. Ensure the enable pin configuration aligns with the system power-up sequence to prevent bus hangs during initialization.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when system design requires isolating bus segments or increasing total bus capacitance beyond 400 pF. It is suitable for mixed-voltage environments where 5 V and 3.3 V devices communicate on the same logical bus structure. Do not place multiple PCA9515A units in series, as the design does not support cascaded configurations.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PCA9515A family of I2C repeaters manufactured by NXP Semiconductors. The 'AD' suffix indicates the SOIC-8 package version. Other variants in the family include the ADP (TSSOP8) and ATP (HWSON8) packages, which share identical electrical characteristics but differ in physical form factor.
