DESCRIPTION The L298 is an integrated monolithic circuit in a 15lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the conBLOCK DIAGRAM

This is an old war horse, still valid especially when used with its companion chip, L297.
Yet, may I suggest to give a look to L6208 as well? It includes both L297 & L298 in the same package with an up to date technology. Advantages are lower parts count, higher efficiency and perhaps a lower price...
L298 is old, sure, but it's still strong!
L298 construction technology is more strong (EMC and noise immunity) than DMOS (L6208) and you can found it into the store near you...probably your newsagent know it and you can easy buy it.
BTW the prices are:
L298 = 3,74 euro

L6208 = 14,20 euro

Maybe an old war horse is still better than a new trojan horse.
With this integrated monolithic circuit I resolved many problems.
