SAA1300
The SAA1300 is for switching on and off the supply lines
of various circuit parts via an I
2
C bus signal. Furthermore,
it can be used to supply current for switching diodes in
radio and television tuners. It contains 5 output stages,
which are capable of supplying up to 85 mA in the ON state
or sinking up to
−100 µA
in the OFF state.
Current limiting and short-circuit protection are included.
The output stages are driven by a shift register/latch
combination which is loaded via data from the I
2
C bus. A
power-on reset of the latches ensures the OFF state of the
output stages (OUT 2 to OUT 5) without data reception
from the I
2
C bus. A subaddressing system allows the
connection of up to three circuits on the same I
2
C bus
lines; one of the outputs (OUT 1, pin 7) can also be used
as an input to select the device via a simple internal A/D
converter.

The I/O output stage (OUT 1) is switched as an input stage after a power-on reset. It depends on the contents of the first
data transmission whether the output stage is switched as an output or remains as an input.
