PCA9600

Dual bidirectional bus buffer

Remark: Two or more SX or SY I/Os must not be interconnected. The PCA9600 design

direction control pin so, instead, slightly different logic LOW voltage levels are used at

PCA9600 will be propagated to SX/SY as a ‘buffered LOW’ with a slightly higher voltage

level. If this special ‘buffered LOW’ is applied to the SX/SY of another PCA9600, that

to its TX/TY output. The SX/SY side of PCA9600 may not be connected to similar buffers

that rely on special logic thresholds for their operation, for example P82B96, PCA9511A,

PCA9515A, ‘B’ side of PCA9517, etc. The SX/SY side is only intended for, and compatible

TX/RX signals of a second PCA9600 or P82B96 if required. The TX/RX and TY/RY I/O

restrictions on the interconnection of the TX/RX and TY/RY I/O pins to other PCA9600s,

for example in a star or multipoint configuration with the TX/RX and TY/RY I/O pins on the

common bus and the SX/SY side connected to the line card slave devices. For more

The PCA9600 is a direct upgrade of the P82B96 with the significant differences

summarized in Table 4.
