C. L293D
The L293 and L293D are quadruple high-current half –H drivers.
The L293 IS designed to provide bidirectional drive currents of up to 1A at voltage from 4.5V to 36V.
The L293D is designed to provide bidirectional drive currents of up to 600-MA at voltages from 4.5V to 36V.
Both devices are designed to drive inductive loads such as relays, solenoids, dc and bipolor stepping motors,
as well as other high-current/high voltage loads in positive-supply applications.
On the L293D, external high-speed output clamp diodes should be used for inductive transient suppression.
A Vcc1 terminal, separate from Vcc2, is provided for the logic inputs to minimize device power dissipation.
The L293 and L293D are characterized for operation from 0ↄC to 70ↄC.
