SA9504
MODE SELECT LOGIC AND
DC CHARACTERISTICS
The SA9504 chip has several modes of operation for which the
selection logic is defined in the following table. Different mode
selections require different portions of the circuit to be active. Modes
from unlisted combinations of logic pins, are not valid.
POWER-UP PROCEDURE
In order for the SA9504 to function correctly as given in Table 1, the
circuit must be reset on power-up as follows:
To apply a reset, both S0 and S1 should be held HIGH
simultaneously (hold time 100 ns minimum), and then released to a
LOW state upon initially powering up the device.
