L293D

XBLW L293D-L293WS PUSH-PULL FOUR CHANNEL DRIVER WITH DIODES General Description The Device is a monolithic integrated high volt-age, 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 chan- nels is equipped with an enable input. A separate supply input is provided for the logic, allowing op- eration at a lower voltage and internal clamp di- odes are included. This device is suitable for use in switching appli- cations 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 L293WS is assembled in a 20 lead surface mount which has 8 center pins connected to- gether and used for heatsinking.
