DESCRIPTION
The L298 is an integratedmonolithiccircuitin a 15-
lead Multiwatt and PowerSO20 packages. It is a
highvoltage,high current dualfull-bridgedriver de-
signedto acceptstandardTTLlogiclevelsanddrive
inductive loads such as relays, solenoids, DC and
steppingmotors.Twoenableinputsareprovidedto
