The PCF85134 acts as an I
transmit data to an I
the acknowledge signals of the selected devices. Device selection depends on the
I
In single device applications, the hardware subaddress inputs A0, A1, and A2 are
normally tied to V
applications A0, A1, and A2 are tied to V
no two devices with a common I
subaddress.
To enhance noise immunity in electrically adverse environments, RC low-pass filters are
provided on the SDA and SCL lines.
Two I
The least significant bit of the slave address is bit R/W. The PCF85134 is a write-only
device. It will not respond to a read access, so this bit should always be logic 0. The
second bit of the slave address is defined by the level tied at input SA0. Two displays
controlled by PCF85134 can be recognized on the same I
The I
condition (S) from the I
slave addresses. All PCF85134s with the same SA0 level acknowledge in parallel to the
slave address. All PCF85134s with the alternative SA0 level ignore the whole I
transfer.
