AC POWER CONTROLLERS
FEATURES: 10 I/Os to Select/Indicate up to ten Power Levels Inputs activated by Touch or Pushbutton Switch Output switches pure and precise AC Power to Load Operates with 50Hz/60Hz line frequency Rugged, latchup-free process technology +10V to +14V operation (Vss-VDD) LS7314, LS7315 (DIP; LS7314-S, LS7315-S (SOIC) - See Figure 1 APPLICATIONS: Universal and shaded-pole motor speed control for modern appliance designs. Eliminates awkward mechanical switch assemblies and multi-tapped motor windings. (See Fig. 4C) Multi-level light switches. (See Fig. 4D) DESCRIPTION: The LS7314 - LS7315 are MOS integrated circuits specifically designed for appliance motor speed control, lighting control, etc. I/Os (PLs) are provided for selecting/indicating from one to ten power levels. The LS7315 is designed for pushbutton control. The LS7314 is designed for touch control. (See Figures 4A and 4B) INPUT/OUTPUT DESCRIPTION: PL1-PL10 (Pins 1-8, 15, 16) Ten inputs/outputs for selecting ten output phase angles (power levels). When no power level is selected (such as after system power-up) PL1-PL10 all act as inputs. When a power level is selected by applying a logic zero at one of these inputs for TH time (See Dynamic Characteristics), the output (TRIG) is turned on at the phase angle selected and the PL input switches status to becom……
