7.16.6 I
The PCF85132 acts as an I
transmit data to an I
the acknowledge signals from the selected devices. Device selection depends on the
I
subaddress.
In single device applications, the hardware subaddress inputs A0 and A1 are normally tied
to V
A0 and A1 are tied to V
two devices with a common I
To enhance noise immunity in electrical adverse environments, RC low-pass filters are
provided on the SDA and SCL lines.

The PCF85132 is a write-only device and will not respond to a read access, therefore bit 0
should always be logic 0. Bit 1 of the slave address byte, that a PCF85132 will respond to,
is defined by the level tied to its SA0 input (V
Having two reserved slave addresses allows the following on the same I
