L293DD ST Motor Driver | 20-SO | 600mA Output Current, 4.5V-36V Supply

Product Overview

The L293DD is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC and stepping motors) and switching power transistors. The L293DD is a push-pull four channel driver with diodes, designed to drive inductive loads. The device is suitable for use in switching applications at frequencies up to 5 kHz. The L293DD is assembled in a 20-lead SO package with a power tab.
