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 become an output in order to drive a display, such
as an LED. It switches back to the input state when another PL
input is activated or when OFF is selected. (See Note 1)
OFF (Pin 10)
If TRIG is on, a logic 0 applied to the OFF input for TH time
turns TRIG output off and switches the selected PL back to the
input state. If TRIG is off, activating OFF leaves the circuit unaffected. Following an OFF activation, TRIG can be turned on
by applying any PL input. (See Note 1)
SYNC (Pin 12)
Input for PLL reference frequency (50Hz/60Hz). All internal
clock frequencies are synchronized with the SYNC input.
CAP (Pin 11)
Input for component connection for the PLL filter capacitor.

LS7314
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)

LSI
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)

FIGURE 1
TRIG (Pin 13)
This output is designed to drive a triac in series with the
load and control its firing angle with respect to the AC line.
A 1ms output pulse width is provided to enable the triac to
fire even with inductive loads which cause significant phase
delays between voltage and current.
Vss (Pin 14)
Supply voltage positive terminal.
VDD (Pin 9)
Supply voltage negative terminal (ground).
NOTE 1: LS7315 has an internal pullup resistor on this input and LS7314 does not. (See DC Electrical Characteristics.)
