DESCRIPTION  
L293D  
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.
