Note 1. UP/DOWN input polarity shown is for LS7534. For LS7535, the polarity is reversed.

Note 2. Points A, D, E and K correspond to minimum brightness, where ø = 41°.

Points B, C, G and H correspond to maximum brightness, where ø = 159°.

Points denoted by M correspond to an arbitrary intermediate brightness.

Note 3. Points F, J and L correspond to ø = 64°. The ramp-up or ramp-down rate of ø changes at these points

(upon long activation only) indicated by the discontinuity of the slopes. The interval E to F or J to K,

in terms of time and angle, are 934ms and 23°, respectively.
