Description
The ST L293d is a four-channel push-pull driver with diodes. This device is a four-channel monolithic integrated high voltage, high current driver that accepts standard DTL or TTL logic levels and drives inductive loads (such as relays, solenoids, DC, and stepping motors) and switching power transistors. Each pair of channels has an enable input to facilitate use as two bridges. The logic has a separate supply input that allows it to operate at a lower voltage, and internal clamp diodes are included. This device can be used in switching applications with frequencies of up to 5 kHz. Its 16-Pin Driving IC is designed to control a pair of motors in any direction at the same time. Its drive current is bidirectional.
