DESCRIPTION
The Device is a monolithic integrated high voltage, 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 transistors.
To simplify use as two bridges each pair of channels is equipped
with an enable input. A separate supply input is provided for the
logic, allowing operation at a lower voltage and internal clamp
diodes are included.
This device is suitable for use in switching applications 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.
