L293E, Двухтактный, четырехканальный драйвер двигателей постоянного тока, [DIP-20-300]
The L293E is a quad push-pull Driver, capable of delivering output currents to 1A per channel. Each channel is controlled by 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. Additionally, the L293E has external connection of sensing resistors, for switch-mode control. The L293E both use the four centre pins to conduct heat to the printed circuit board.
• Output Current 1A Per Channel
