... Yes — IN only — 3 Product data sheet PCA9510; PCA9511 DESCRIPTION Chip enable pin. Grounding this pin puts the part in a low current (<1 A) mode. It also disables the rise time accelerators, isolates SDAIN from SDAOUT and isolates SCLIN from SCLOUT. Serial clock output to and from the SCL bus on the card ...

... During positive bus transitions current source is switched on to quickly slew the SDA and SCL lines high once the input level of 0.6 V for the PCA9511 is exceeded. The rising edge rate should be at least 1. guarantee turn on of the accelerators. The PCA9510 doesn’t have any rise time accelerator circuitry. ...

... SDA SCL NOTE: The PCA9510 and PCA9511 can be used in any combination depending on the number of rise time accelerators that are needed by the system. Normally only one PCA9511 would be required per bus. Figure 9. Hot swapping multiple I/O cards into a backplane using the PCA9510 and PCA9511 in a CompactPCI, VME, and 2004 Oct 05 PCA9510 ...
