DESCRIPTION
The Device is a monolithic integrated high volt-
age, high current four channel driver designed to
accept standardDTL 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 equippedwith an enable input. A separate
supply input is provided for the logic, allowing op-
eration at a lower voltage and internal clamp di-
odes areincluded.
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-
getherand usedfor heatsinking
The L293DD is assembled in a 20 lead surface
mount which has 8 center pins connected to-
getherand usedfor heatsinking.
