Toggle Latch

Where "1" is On and "0" is Off, each state change of the Toggle Input from Off to On changes the
state of the Toggle Output. (see: Table 9)
Toggle Input Previous Toggle Output
The switching application provides eight instances of three-input logic operations.
The Logic (Combinatorial Logic) function provides the Switching Application the ability to take up to
three signals and logically combine them using Boolean logic to create a logical signal. The three-
input lookup table allows any binary function of three variables to be realized. The outputs of the
logic functions may be used as inputs to other logic functions (allowing logic functions of more than
three inputs to be realized) or as inputs to other types of functions.
Each Logic Function has the following input signals:
• Input A – first input to the logic function
• Input B – second input to the logic function
• Input C – third input to the logic function
Each Logic function has the following output signals:
• Logic Output – the logical output of the of Input A, Input B, and Input C as defined by
the lookup table
