... NXP Semiconductors Table 3. Pin SDAA SCLA Fig 4. 6.3.2 Port A (CECA) CECA does not have a rise time accelerator, but has a standard open-drain I/O. In addition to incurring no offset voltage, it has edge rate control and a lower capacitance than those of standard discrete MOSFET, and isolates the input/output capacitance designed for a lower speed channel for consumer electronic control (less than 10 kHz) or general purpose interrupt or reset over long cable ...

... NXP Semiconductors 6.3.3 Port B (SDAB, SCLB, CECB) SDAB and SCLB are standard I accelerator. The static level offset produces an output LOW of 0.5 V (typical mA. As with the standard I levels. The size of these pull-up resistors depends on the system requirement, and should meet the current sinking capability of the device that drives the buffer, as well as that of the buffer. The minimum and maximum pull-up resistors are determined and the pull-up resistor’ ...

Sink or LCD TV application According C-bus, a comparator detects the falling edge when it goes below 0.3V the internal driver on port B to turn on, causing port B to pull down to about 0.5 V. When port B of the PCA9527 falls, first a CMOS hysteresis type input detects the falling edge and causes the internal driver on port A to turn on and pull the port A pin down to ground ...
