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 highvoltagepower
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 connectedtogetherand
used for heatsinking.
