On/Off Control
The on/off control is achieved by using the on/off pin on the input
side of SIPF150. The circuit for the remote on/off circuitry consists
of an active low TTL switch. When the circuit is open, the IC Vcc
is cut off. When the circuit is closed, IC Vcc is activated. A
mechanical switch or a TTL/CMOS gate needs to be placed
between the remote on/off pin and ground creating a condition
where the circuit is closed to activate the inverter. Either one of the
following will be required for the inverter to operate:
One recommended use of logic switch for remote on/off is shown
in the diagram below. Electrical specification for on/off terminal is
Low 0 to 0.4V, -0.4 mA or higher when switch is closed.

To IC Vcc
1. Tie on/off pin to ground.
2. Add mechanical switch between on/off pin and ground, close switch.
3. Add TTL/CMOS switch between on/off and ground. Circuit must be closed for
unit to operate (as shown above right).
