L293D motor driver

Description

The L293D accepts TTL logic input and controls the motor. This chip has an internal output switch, allowing voltage and current to be safely transmitted to the motor. Mainly used to control motors in robots, RC cars, automation systems, etc. This motor driver is suitable for controlling motors with relatively low currents and speeds.

The texts in the PDF file :

The Device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors. To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. 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 together and used for heatsinking The L293DD is assembled in a 20 lead surface mount which has 8 center pins connected together and used for heatsinking.
