■ Driving by IC
An IC on which multiple driving transistors are integrated is available.
The designing of the circuit or PCB to drive multiple relays, a small-
size solenoid, or a small-size lamp can be simplified by using this IC.
Consult the manufacturer of the IC for details. For V

■ Driving by TTL
TTLs can be divided into two types by classification of the output:
totem-pole and open-collector outputs. Connection of each type of
TTL is described below.
Use a diode as surge suppressor.
In the specifications of some ICs, such a phrase as “fan-out 10” may
be used in place of the legend I
TTLs can be connected in parallel. In terms of current, fan-out 1
equals 1.6 mA. Hence,
Fan-out n = 1.6 x n (mA)

■ Driving by Other Switching
Consult the manufacturer of the switching device. The upper- and
lower-limit values of the pickup voltage can be determined in the
same manner as described in Upper-limit Pickup Voltage and Lower-
limit Pickup Voltage.
