(1) The TRIG Phase Angles shown in TABLE 1 are referenced
to the SYNC input. Ø values are mask programmable.
(2) The percentage of Full Power delivered to a resistive load
by the Triac Switch.
FIGURE 4C and 4D NOTES
NOTE 1: Value for 5mA LEDs.
NOTE 2: Use zener which produces 6.2V ±5% at 500µA or
less, i. e. P/N MZ4627.
NOTE 3: R6-C6 Snubber Network may be required for large
inductive loads.
NOTE 4: Tie all unused touch inputs together and return to Vss
through 100k Ohm, 1/4W resistor.
NOTE 5: The AC Mains Polarity shown is required for Touch
Control applications.
