(1) The TRIG Phase Angles shown in TABLE 1 are referenced to the

SYNC input. In the Application Schematic shown in Figure 4A,

SYNC is delayed by 7° from the AC line. Therefore, actual Phase

Angles with respect to the AC line are 7° less than TABLE 1 values.

TABLE 1 values are mask programmable.

(2) The percentage of Full Power delivered to a resistive load by the

Triac Switch.

FIGURE 4 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.
