... 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 I²C slave address is different. This allows devices (eight CAT9554 and eight CAT9554A connected on the same bus ...

... CAT9554, CAT9554A PIN DESCRIPTION SCL: Serial Clock The serial clock input clocks all data transferred into or out of the device. The SCL line requires a pull-up resistor driven by an open drain output. SDA: Serial Data/Address The bidirectional serial data/address pin is used to transfer all data into and out of the device. The SDA pin is an open drain output and can be wire-ORed with other open drain or open collector outputs ...

... CAT9554/9554A for a read or write operation. The four most significant bits of the slave address are fixed as binary 0100 for the CAT9554 (Figure 6) and as 0111 for the CAT9554A (Figure 7). The CAT9554/9554A uses the next three bits as address bits. ...

... CAT9554, CAT9554A ACKNOWLEDGE After a successful data transfer, each receiving device is required to generate an acknowledge. The acknowledging device pulls down the SDA line during the ninth clock cycle, signaling that it received the 8 bits of data. The SDA line remains stable LOW during the HIGH period of the acknowledge related clock pulse (Figure 5) ...

... CAT9554, CAT9554A The output port register sets the outgoing logic levels of the I/O ports, defined as outputs by the configuration register. Bit values in this register have no effect on I/O pins defined as inputs. Reads from the output port register reflect the value that is in the flip-flop controlling the output, not the actual I/O pin value ...
