Operation Description (Cont’d):
Alarm Off Input:
Connecting this input pin to VSS inhibits the alarm output momentarily. An internal pull–down resistor
is provided.
Sleep Timer and Sleep Output:
The sleep output can be used to keep the radio turned on for any period of time up to 59 minutes or
1 hour 59 minutes. Table 2 shows how to select the period (59 minutes or 1 hour 59 minutes). This
sleep timer uses a down counter. When the counter contents reach [00], the output stops being deliv-
ered, turning off the radio. By connecting “Snooze Input” to VSS at the sleep output on–state, the sleep
output is inhibited.
