L293d L293dd push-pull four channel driver with diodes 600ma output current capability per channel 1.2a peak output current (non repeti- tive) per channel enable facility overtemperature protection logical o0o input voltage up to 1.5 v (high noise immunity) internal clamp diodes 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 tran- sistors. 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 L293dd is assembled in a 20 lead surface mount which has 8 center pins connected to- gether and used for heatsinking. june 1996 block diagram so(12+4+4) powerdip (12+2+2) ordering numbers: L293dd L293d 1/7
