OSCD
OSCD is an output timing oscillator input pin. It is con-
nected to an external RC to obtain the desired output
turn-on duration. Variable output turn-on durations can
beachievedbyselectingvariousvaluesofRCorusinga
variable resistor.
RELAY (TRIAC)
RELAY is an output pin set as a RELAY driving (active
high)outputfortheHT761XA,orasaTRIACdriving(ac-
tive low) output for the HT761XB.

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 disabled. The input disable to enable debounce
time is 5 seconds. Connect this pin to VDD when this
function is not used. The CDS input is ignored when the
output is active.

VDD
ON
Output is always ON:
RELAYoutputshighforrelaydriving.
TRIAC pulse train output is syn-
chronized by ZC for triac driving.
VSS
OFF
Output is always OFF:

Open
AUTO
Outputs remain in the off state until
activated by a valid PIR input trigger
signal. When working in the AUTO
mode, the chip allows override con-
trol by switching the ZC signal.
