The PCA9600 has two identical buffers allowing buffering of SDA and SCL I
signals. Each buffer is made up of two logic signal paths, a forward path from the I
interface, pins SX and SY which drive the buffered bus, and a reverse signal path from the
buffered bus input, pins RX and RY to drive the I
The rest of this discussion will address only the ‘X’ side of the buffer; the ‘Y’ side is
identical.
