STMicroelectronics L239B

The L293B and L293E are quad push-pull drivers capableof delivering output currents to 1A per channel. Each channel is 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.

DESCRIPTION

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 switchmode control. The L293Band L293E are package in 16 and 20-pin plastic DIPs respectively ; both use the four center pins to conduct heat to the printed circuit board.
