L293E

LINEAR INTEGRATED CIRCUITS PUSH-PULL FOUR CHANNEL DRIVERS PRELIMINARY DATA The L293 and the L293E are monolithic integrated high voltage, high current four channel drivers in dual in-line plastic package with 16 leads and 20 leads respectively. They are designed to accept standard DTL or TTL input logic levels and drive inductive loads (such as relays, solenoids, DC and stepping motors) and switching power transistors. Both are provided of complementary push-pull output stage, two inhibit inputs (which disable two channels each), and an additional supply inputs so that the logic circuitry may run at a lower voltage to reduce power dissipation. In the L293E the emitters of the lower transistors of each push-pull stage are not internally grounded and the corresponding pins can be used for the connection of an external sensing resistor, making very easy switch-mode current control. . The main features of the L293 and of the L293E are: 1A output current capability per channe...
