·
After mains connection and simultaneous TRUE at both inputs, the outputs are set as
follows:
Inputs Outputs
bCw_b bCCw_b bCwCCw_b bQSP_b
1 1 0 1
0 = FALSE
1 = TRUE
·
The following truth−table results only if the inputs were set to TRUE once after power
switch−on
Inputs Outputs
bCw_b bCCw_b bCwCCw_b bQSP_b
0 0 0 1
1 0 1 0
0 1 1 0
1 1 unchanged unchanged
0 = FALSE
1 = TRUE
If you set both inputs to TRUE during operation, both outputs still have their previous output value.
