DESCRIPTION
The L298 is an integrated monolithic circuit in a 15-
lead Multiwatt and PowerSO20 packages. It is a
high voltage, high current dual full-bridge driver de-
signed to accept standardTTL logic levels and drive
inductive loads such as relays, solenoids, DC and
stepping motors. Two enableinputs are provided to
enableor disable the deviceindependentlyof the in-
put signals. The emitters of the lower transistors of
each bridge are connected together and the corre-
sponding external terminal can be used for the con-
