Description
General description
The PCA9515A is a CMOS integrated circuit intended for application in I2C-bus and SMBus systems. While retaining all the operating modes and features of the I2C-bus system, it permits extension of the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines, thus enabling two buses of 400 pF.
The I2C-bus capacitance limit of 400 pF restricts the number of devices and bus length. Using the PCA9515A enables the system designer to isolate two halves of a bus, thus more devices or longer length can be accommodated. It can also be used to run two buses, one at 5 V and the other at 3.3 V or a 400 kHz and 100 kHz bus, where the 100 kHz bus is isolated when 400 kHz operation of the other is required.
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 across the repeater
• Accommodates Standard-mode and Fast-mode I2C-bus devices and multiple masters
• 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
Alternatives
