Notes 1. Circuit types enclosed in brackets indicate Schmitt trigger input.

*

2. BP0 through BP7 select VLC1 as an input source.

However, the output levels change depending on the external circuit of BP0 through BP7 and VLC1.

* Example Because BP0 through BP7 are mutually connected inside the µPD75P3036, the output levels of BP0 through

BP7 are determined by R1, R2, and R3.
