资 源 简 介
The Device is a monolithic integrated high voltage,high current four channel driver designed toaccept standard DTL or TTL logic levels and driveinducTIve loads (such as relays solenoides, DCand stepping motors) and switching power transistors.To simplify use as two bridges each pair of channelsis equipped with an enable input. A separatesupply input is provided for the logic, allowing operaTIonat a lower voltage and internal clamp diodesare included.This device is suitable for use in switching applicaTIonsat frequencies up to 5 kHz.The L293D is assembled in a 16 lead plasTIcpackaage which has 4 center pins connected togetherand used for heatsinkingThe L293DD is assembled in a 20 lead surfacemount which has 8 center pins connected togetherand used for heatsinking.
