The 1 MHz data rate is the maximum the buffer can pass without introducing timing violations. The 10 pF input capacitance is low enough that adding the buffer to an existing bus node does not significantly load the upstream master.
Yes, the part is rated for 1 MHz maximum data rate and has a 10 pF input capacitance, so it can buffer a 1 MHz bus without exceeding its own timing or loading limits. Verify the total bus capacitance and propagation delay against the master's timing budget.
The PCA9600D operates from 2.5 V to 15 V and supports 1 MHz, while the PCA9515 typically runs from 2.7 V to 5.5 V and supports 400 kHz. The PCA9600D's wider supply range and higher data rate make it the choice for mixed-voltage or high-speed I²C buses; the PCA9515 is a lower-cost option for standard 3.3 V/5 V 400 kHz buses.
The PCA9600D's 5.2 mA supply current and 10 pF input capacitance suggest it can drive a bus segment with several slave devices, but the exact fan-out depends on the total bus capacitance (including trace and device input capacitance) and the rise-time requirements at the operating frequency. At 1 MHz, keep total bus capacitance under 400 pF; at 400 kHz, up to 400 pF is typical.
