L293DLED Drivers Product Details

General Description

The Device is a monolithic integrated high volt-age,high current four channel driver designedtoacceptstandard DTL or TTL logic levels and driveinductive loads(such as relays solenoides,DCandsteppingmotors)and switching power tran-sistors.

To simplify use as two bridges each pair of chan-nels is equipped with an enable input.A separatesupplyinput is provided for the logic,allowing op-eration at a lower voltage and internal clamp di-odesareincluded.

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 andused for heatsinking

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