این آی سی یک نوع درایور برای موتور های DC میباشد پکیج این آی سی از نوع DIP بوده و دارای 16 پایه است

The L293B and L293E are quad push-pull drivers capableof deliveringoutputcurrents to 1Aperchan nel. Each channelis controlledby a TTL-compatible logic input and each pair of drivers (a full bridge) is equipped with an inhibit input which turns off all four transistors. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation.
