... Fm+ I (Ref. 1). More than one PCA9646 may be used in series, providing a substantial fan-out capability. As per the PCA9525 and PCA9605 simple bus buffers, the PCA9646 includes a unidirectional buffer for the clock signal, and a bidirectional buffer for the data signal ...

... The power supply voltage for the PCA9646 may be any voltage in the range 2 5.5 V. The IC supply must be common with the supply for the bus. Hysteresis on the ports are a percentage of the IC’s power supply, hence noise margin considerations should be taken into account when selecting an operating voltage. ...

... The RESET signal will clear the contents of the Control register, which has the effect of disabling all output lines SC[0:3] and SD[0:3 the nature of the I devices may become ‘stuck’. To help in the clearing of this condition, the PCA9646 can be reset, and each port brought on-line successively to find the component holding the bus LOW ...

... The PCA9646 is always addressable from the SCL/SDA side, regardless of the state of B7. Any device which can communicate data to the SCL/SDA pins, either by being directly attached to those pins or by transmitting through the PCA9646 (when B7 = 1), may address the device and change the control register’s contents. The Control register is only updated upon receipt of the STOP condition ...

... P82B715 systems have a finite capacitance limit and its system calculations can be relatively complex. The buffering action of PCA9646 simplifies calculations and allows the isolated bus rise time to meet the Fast-mode requirement even when that is not possible on the long cable section. ...

... NXP Semiconductors The PCA9646 may also be driven in series. scenario, each of the four outputs of the first device (U2) has six more PCA9646’s connected to it. Each of those six devices has four outputs, thus giving 4 7 112 outputs. If the RESET pin on U2 was also driven from the master, it would be possible to reproduce this entire structure multiple times, giving a truly massive address space capability ...
