The L293 and L293D devices are quadruple high- 1• Wide Supply-Voltage Range: 4.5 V to 36 V current half-H drivers. The L293 is designed to • Separate Input-Logic Supply provide bidirectional drive currents of up to 1 A at • Internal ESD Protection voltages from 4.5 V to 36 V. The L293D is designed • High-Noise-Immunity Inputs to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are • Output Current 1 A Per Channel (600 mA for designed to drive inductive loads such as relays, L293D) solenoids, DC and bipolar stepping motors, as well as • Peak Output Current 2 A Per Channel (1.2 A for other high-current/high-voltage loads in positiveL293D) supply applications. • Output Clamp Diodes for Inductive Transient Each output is a complete totem-pole drive circuit, Suppression (L293D) with a Darlington transistor sink and a pseudoDarlington source. Drivers are enabled in pairs, with 2 Applications drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN
