DESCRIPTION

The L293Cis a monolithichigh voltage,high current integratedcircuit four channel driver in a 20 pin DIP. It is designed to accept standard TTL or DTL input logic levels and drive inductive loads (such as relays, solenoids, DC and stepping motors) and switching power transistors.

The device may easily be used as a dual H-bridge driver: separatechip enable andhighvoltagepower supply pins are provided for each H-bridge. In addition, a separate power supply is provided for the logic section of the device.

The L293C is assembled in a 20 lead plastic package which has4 centerpinsconnectedtogetherand used for heatsinking.
