The texts in the PDF file :

The L298 is a power integrated circuit usable for driving resistive and inductive loads. This device contains four push-pull drviers with separate logic inputs. Two enable inputs are provided for power down and chopping. Each driver is capable of driving loads up to 2A continuously.

Logic input to the L298 have high thresholds (1.85V) and hysteresis to provide trobule-free operation in noisy environments normally associated with motor and inductors. The L298 input currents and threholds allow the device to be driven by TTL and CMOS systems without buffering or level shifting.

The emitters fo the low-side power drviers are separately available for current sensing. Feedback from the emitters can be used to control load current in a swtiching mode, or can be used to detect load faults.
