L293DD is a push-pull four channel driver with diodes. This article mainly introduces pinout, datasheet, features and other details about L293DD.
IC MTR DRV BIPOLR 4.5-36V 20SOIC L293DD is a push-pull four channel driver with diodes.

The L293DD is a monolithic integrated high voltage, high current four channel driver designed toaccept standard DTL or TTL logic levels and driveinductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.
This device is suitable for use in switching applications at frequencies up to 5 kHz. The L293D is assembled in a 16 lead plastic packaage which has 4 center pins connected to gether and used for heatsinking The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected to gether and used for heatsinking.
