The LB and LE are quad push-pull drivers capable of delivering output currents to 1A per channel. Each channel is controlled by a TTL-compatible logic input and each xatasheet 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.


Additionally, the LE has external connection of sensing resistors, for switchmode control.
