4. The SHUTDOWN pin is an open drain CMOS/
TTL compatible output which should be tied to the
TTL compatible input of an eventual control block.
The absolute maximum rating of this output is 7V.
In the case of a visual alarm, a LED is likely to be
tied to the positive power supply which can be de-
structive for the Shutdown output if the power sup-
ply is over 7V. An easy way to eliminate this is to
add a 6V zener diode between the Shutdown out-
put and the Ground as shown on figure 10.
