Key Features
- Dual bidirectional I2C and SMBus bus repeater with 400kHz Fast-mode support
- Integrated level translation for mixed 3.3V/5V system designs
- Hot-swap capable for live board insertion without bus disruption
- 8-Pin SOIC compact package ideal for space-constrained designs
- Active low OE pin for easy enable/disable control
Applications
The PCA9515AD is widely used in server and industrial systems requiring I2C bus extension and signal isolation between voltage domains. It is ideal for hot-swap backplane designs, SMBus management buses in telecom equipment, and multi-master I2C systems where bus buffering and fanout expansion are needed. Its level-shifting capability makes it a common choice in mixed 3.3V/5V embedded platforms.

Frequently Asked Questions
What is the maximum operating frequency of the PCA9515AD?
The PCA9515AD supports Standard-mode (100kHz) and Fast-mode (400kHz) I2C and SMBus protocols. It does not support Fast-mode Plus (1MHz) or High-speed mode (3.4MHz), so verify your system's speed requirements before selecting this device.
Can the PCA9515AD translate voltage levels between 3.3V and 5V I2C buses?
Yes, the PCA9515AD supports mixed-voltage operation and can interface between 3.3V and 5V I2C/SMBus segments. Its open-drain architecture and separate VCC pins per port allow connection to buses operating at different supply voltages.
What package is the PCA9515AD available in and what are the alternatives?
The PCA9515AD is available in an 8-Pin SOIC (Small Outline IC) package. Functionally equivalent alternatives include the PCA9515ADP (TSSOP-8 package) and other I2C bus buffers such as the TCA4307 which offers additional fault protection features.
What is the typical supply current for the PCA9515AD?
The PCA9515AD typically draws around 500µA quiescent current when idle. Total supply current depends on bus loading and switching frequency, but it is designed to minimize power consumption in both active and standby states.
