MTL4510B modes
The following logic and timing diagrams are provided to assist the user in understanding the behaviour of the MTL4510B module
when a specific
mode
is chosen.
The open switch (
) and closed switch (
) symbols are used to represent both the input conditions of Ch A, Ch B, Ch C or
Ch D and then the output conditions of o/p 1, 2, 3 or 4.
How to use these mode tables - examples
The logic tables (right) for Mode 1 represent Ch A controlling outputs
1 & 3, while Ch C controls outputs 2 & 4.
Output 1 & 3 are shown following input Ch A (open or closed) while
Outputs 2 & 4 follow input Ch C.
Mode 2 however shows o/p 3 and 4 being in antiphase to their
inputs.
