资 源 简 介

The L293, L293E and L298 each contain four pushpull powerdriverswhich can be used independently or,more commonly, as two full bridges. Each driver is controlled by a TTL-level logic input and each pair of drivers is equipped with an enable input which controls a whole bridge. All three devices feature aseparate logic supply input so that the logic can be run on a lower supply voltage, reducing dissipation.This logic supply is internally regulated.
