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.
