L293DD SGS-THOMSON Push-Pull Four Channel Driver Data Sheet
Download Datasheet for SGS-Thomson Microelectronics L293DD Push-Pull Four Channel Driver With Diodes [7 pages 1996 pdf/zip]
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.
