P82B715D

Специализированный интерфейс, 4.5 В, 12 В, 8 вывод(-ов).

The P82B715D is an I?C Bus Extender buffers both the serial data (SDA) and serial clock (SCL) signals on the I?C bus and allows for extension of the I?C bus, while retaining all the operating modes and features of the I?C system. The I?C bus capacitance limit of 400pF restricts practical communication distances to a few meters. The advantages of the P82B715 is that it can isolate bus capacitance such that the total loading (devices, connectors, traces and wires) of the new bus or remote I?C nodes are not apparent to other I?C buses (or nodes). This is achieved by using one P82B715 device at each end of a long cable. The pin Lx of one P82B715 device has to be connected to Lx of the second P82B715 (similarly for Ly). This allows the total system capacitance load to be around 3000pF.
