2.9
Usually this pin is connected to the feedback electrode
through a current limiting resistor. If not used, this pin
must be connected to V
When the horn is enabled, FEED drives the buffered
output HS pin and the complementary output HB pin.
2.10
This pin is an open drain NMOS output used to drive a
visible LED.
2.11
A capacitor connected to this pin, with a parallel
resistor, sets the internal clock low time, which is
approximately the clock period.
2.12
A resistor between this pin and COSC pin sets the
internal clock high time. This also sets the IRED pulse
width.
2.13
In Timer mode, this input pin can be used to set an
external smoke comparator reference.
2.14
This input is used to invoke two test modes and the
Timer mode. This input has an internal pull-down.
