L293D IC Dual H-Bridge Motor Driver IC

 100

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 solenoids, 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 package that has 4
center pins connected together and used for heatsinking.
