*1.

: Schmitt triggered input

2. BP0 to BP7 select VLC1 as the input source.

However, the output level depends on BP0 to BP7 and VLC1 external circuit.

Example

BP0 to BP7 are connected mutually within the

µPD75316B. Therefore, the output level of BP0 to BP7

is determined by the value of R1, R2 and R3.
