STMicroelectronics | L293B

The L293B is a quad push-pull drivers capable of delivering output currents to 1A per channel. Each channel is controlled by a TTLcompatible 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.

The L293B and L293E are package in 16 and 20-pin plastic DIPs respectively; both use the fourcenter pins to conduct heat to the printed circuit board.

Features:

• Output Current 1 A Per Channel
• Peak Output Current 2 A per Channel (non repetitive)
• Inhibit Facility
• High Noise Immunity
• Seperate Logic Supply
• Overtemperature Protection
