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
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 L293DD is assembled in a 20 lead surface
mount which has 8 center pins connected to
gether and used for heatsinking.
