PCA9515APW, Специализированный интерфейс, I2C, Последовательный, SMBus, I2C Шина и SMBus Системные Применения

The PCA9515APW is a dual-channel bidirectional I?C Buffer is operational at 2.3 to 3.6-V VCC. It is a BiCMOS integrated circuit intended for I?C bus and SMBus systems applications. The device contains two identical bidirectional open-drain buffer circuits that enable I?C and similar bus systems to be extended without degradation of system performance. It buffers both the serial data (SDA) and serial clock (SCL) signals on the I?C bus, while retaining all the operating modes and features of the I?C system. This enables two buses of 400pF bus capacitance to be connected in an I?C application. The I?C bus capacitance limit of 400pF restricts the number of devices and bus length. Using this buffer enables the system designer to isolate two halves of a bus, accommodating more I?C devices or longer trace lengths. It has an active-high enable (EN) input with an internal pull-up, which allows the user to select when the repeater is active.

• Active-high repeater-enable input
• Lock-up free operation
• Powered-OFF high-impedance I?C-bus pins
• Accommodates standard-mode and fast-mode I?C devices and multiple masters
