... Zero offset output voltage allows multiple PCA9508s to be put in series and still maintains an excellent noise margin. PCA9508 has B side and A side bus drivers. The 2 5.5 V bus B side drivers behave much like the drivers on the PCA9515A device, while the adjustable voltage bus A side drivers drive more current and incur no static offset voltage ...

... V above 0 used to provide the 0.5V good detect circuit. The PCA9508 logic and all I/Os are powered by the V An undervoltage/initialization circuit holds the PCA9508 in a disconnected state which presents high-impedance to all SDA and SCL pins during power-up. A LOW on the enable pin (EN) also forces the parts into the disconnected state ...

... The EN pin should only change state when the global bus and the repeater port are in an idle state to prevent system failures. If the PCA9508 is enabled while the bus is active, the PCA9508 will connect at the first STOP signal or at the first gap in activity that satisfies the internal idle bus time after the enable sequence is complete ...

... V I Master devices can be placed on either bus. Fig 4. The PCA9508 tolerant does not require any additional circuitry to translate between 0 5.5 V bus voltages and 2 5.5 V bus voltages. When the A side of the PCA9508 is pulled LOW by a driver on the I detects the falling edge when it goes below 0.5V B side to turn on, causing the B side to pull down to about 0.5 V. When the B side of the PCA9508 falls, fi ...

NXP Semiconductors On the B bus side of the PCA9508, the clock and data lines would have a positive offset from ground equal to the V be pulled to the V the end of the acknowledge, the level rises only to the LOW level set by the driver in the PCA9508 for a short delay while the A bus side rises above 0.5V HIGH ...
