DESCRIPTION

The L293C is a monolithic high voltage, high current

integrated circuit 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 re-

lays, solenoids, DC and stepping motors) and

switching power transistors.

The device may easily be used as a dual H-bridge

driver : separate chip enable and highvoltage power

supply pins are provided for each H-bridge. In addi-

tion, a separate power supply is provided for the

logic section of the device.

The L293C is assembled in a 20 lead plastic pack-

age which has 4 centerpins connected togetherand

used for heatsinking.
