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)

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)
