PCA9515APWR - Brand New Texas Instruments Signal Buffers, Repeaters, Splitters
-
Description
The PCA9515APWR is a CMOS integrated circuit designed for application in I2C-bus and SMBus systems. It allows for the extension of the I2C-bus by buffering both the data (SDA) and clock (SCL) lines, enabling two buses of 400 pF. By using the PCA9515APWR, system designers can isolate two halves of a bus, allowing for more devices or longer bus length. It also supports the operation of two buses at different voltages or frequencies.
Specifications and Features
- 2-channel, bidirectional buffer
- I2C-bus and SMBus compatible
- Active HIGH repeater enable input
- Open-drain input/outputs
- Lock-up free operation
- Supports arbitration and clock stretching
- Accommodates Standard-mode and Fast-mode I2C-bus devices
- Powered-off high-impedance I2C-bus pins
- Operating supply voltage range of 2.3 V to 3.6 V
- 5.5 V tolerant I2C-bus and enable pins
Application Scenarios
The PCA9515APWR is ideal for use in systems that require the extension of the I2C-bus, such as in industrial automation, smart home devices, and automotive electronics. It can be used to connect multiple devices and extend the bus length, providing more flexible and scalable system designs.
