NOTES
1) All circuits connected by broken lines are optional.
2) C7 is used only with electronic extension and R7 is used only with mechanical switch.
3) See I/O Description for MODE (Pin 2)
4) Use Connection A when Neutral is not available. Use Connection B when Neutral is available.
5) Connection between Pin 6 & Pin 7 should be broken when EXT is used.

APPLICATION EXAMPLE:
A typical implementation of a lamp dimmer circuit is shown
in Fig. 5. Here the brightness of the lamp is set by touching
the Touch Plate. The functions of different components are
as follows:
R1, C2 and C5.
R2 and C4 generate the filtered signal for the SYNC
input for synchronizing the internal PLL with the line
frequency.
R3 and C7 act as a filter circuit for the electronic
extension. If extensions are not used, the EXT input
(Pin 6) should be tied to V
DD
(Pin 7).
R4, R5, R6 set up the sensitivity of the SENS input.
C6 provides noise filtering.
C3 is the filter capacitor for the internal PLL.
R8 provides current limiting and isolation between the
chip output and the triac gate.
C1 and L are RF filter circuits.
The 15V DC supply for the chip is provided by Z, D1,
In the case of momentary power failure, the circuit state
remains unchanged for a period of up to 1 sec. For longer
power interruptions, the output is shut off.

EXTENSIONS:
All switching and dimming functions can be implemented by utilizing the
EXT input. This can be done by either a pushbutton switch or the elec-
tronic switch in conjunction with a Touch Plate, shown in Figure 6.
When the plate is touched, a logic high level is generated at the EXT
input of the IC for both half- cycles of the line frequency. (See Figure 5)
