2 / 19 page L293, L293D QUADRUPLE HALFH DRIVERS SLRS008C − SEPTEMBER 1986 − REVISED NOVEMBER 2004 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 description/ordering information (continued) On the L293, external high-speed output clamp diodes should be used for inductive transient suppression. A VCC1 terminal, separate from VCC2, is provided for the logic inputs to minimize device power dissipation. The L293and L293D are characterized for operation from 0 °C to 70°C. block diagram 1 0 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1 2 1 0 1 1 0 2 4 3 M M M 1 0 1 0 1 0 VCC2 VCC1 NOTE: Output diodes are internal in L293D.
