Functional Description
VEE
VE E supplies power to the analog front end
circuit with a stabilized voltage which is –4V
with respect to VDD normally.
OSCS
OSCS is a system oscillator input pin. When it
is connected to an external RC a system fre-
quency of 16K Hz can be generated.
OSCD
OSCD is an output timing oscillator input pin.
It’s connected to an external RC to obtain the
desired output turn-on duration. Variable out-
put turn-on durations can be achieved by select-
ing various values of RC or using a variable
resistor.
RELAY (TRIAC)
RELAY is an output pin set as a RELAY driving
(active high) output for the HT761XA, or as a
TRIAC driving (active low) output for the
HT761XB.
The output active duration is controlled by the
OSCD oscillating period.

CDS
CDS is a CMOS schmitt trigger input structure.
It is used to distinguish between day time and
night time. When the input voltage of CDS is
high the PIR input is enabled. On the other
hand, when CDS is low the PIR input is dis-
abled. The input disable to enable debounce
time is 5 seconds. Connect this pin to VDD
when not using this function. The CDS input is
ignored when the output is active.
