V
DD
(pin 1)
This pin is the positive supply pin, and should
always be the most positive point in the circuit.
Internal circuitry connected to this pin is used to
provide power on reset of the microprocessor, so
an external reset signal is not required. Refer to the
Electrical
Characteristics
information.

M2 (pin 2), M1 (pin 3) and M0 (pin 4)
The digital levels at these pins determine the mode
of operation, as shown in Table 1 below. Levels are
read whenever the LDR input signal changes, so
that modes can be changed ‘on the fly’.
LDR (pin 5)
This is the voltage sensing input pin. It uses Schmitt
trigger circuitry, and a peak detecting circuit for line
frequency filtering so that slowly varying and
pulsating signals will not cause circuit instability. A
logic low level on this pin will be interpreted as the
presence of light, while a logic high results in a dark
input. See the Example Applications section for
typical connections.
Dark (pin 6) and Light (pin 7)
These are the two active high circuit outputs.
Depending on the mode selected, they will either
remain continually active, or provide a 50 msec
pulse output on change from light to dark (Dark
output) or dark to light (Light output).
V
SS
(pin 8)
Circuit common is connected to this pin. This is the
most negative point in the circuit.
