... The device’s extended addressing capability allows devices to share the same bus. The CAT9554A is identical to the CAT9554 except the fixed part of the I slave address is different. This allows devices (eight CAT9554 and eight CAT9554A connected on the same bus ...

... V Data is transmitted to the CAT9554/9554A registers using the write mode shown in Figure 9 and Figure 10. The CAT9554/9554A registers are read according to the timing diagrams shown in Figure 11 and Figure 12. Once a command byte has been sent, the register which was addressed will continue to be accessed by reads until a new command byte will be sent ...
