Tuner switching circuit SAA1300

The SAA1300 is for switching on and off the supply lines
of various circuit parts via an I2C 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 I2C 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
connection of up to three circuits on the same I2C 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.
