Texas Instruments LM293D

LM293D Description

The L293D IC is a common Motor Driver IC that allows a DC motor to rotate in any direction. The L293D driver has 16 pins and is used to operate a set of two DC motors in any direction at any time. It means that we can control two DC motors with an L293D IC.
L293D driver can also run small and silent large motors. This L293D IC operates on the H-bridge concept, which allows electricity to flow in any direction.
