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 frequenciesup 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.
