The L293 is designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V. The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, dc and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications. 1 HEAT SINK AND GROUND 1 28 2 27 3 26 4 25 5 24 6 23 7 22 8 21 9 20 NC NC 2Y 2A 10 19 11 18 12 17 13 16 VCC2 14 15 VCC1 4A 4Y NC NC NC HEAT SINK AND GROUND NC NC 3Y 3A 3,4EN All inputs are TTL compatible. Each output is a complete totem-pole drive circuit, with a Darlington transistor sink and a pseudo-Darlington source. Drivers are enabled in pairs, with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN. When an enable input is high, the associated drivers are enabled and their outputs are active and in phase with their inputs. When the enable input is low, those drivers are disabled and their outputs are off and in the high-impedance state. With the proper data inputs, each pair of drivers forms a full-H (or bridge) reversible drive suitable for solenoid or motor applications. 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 0C to 70C.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values are with respect to the network ground terminal. 2. For operation above 25C free-air temperature, derate linearly at the rate of 16.6 mW/C. 3. For operation above 25C case temperature, derate linearly at the rate of 71.4 mW/C. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation. 4 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 L293, L293D QUADRUPLE HALF-H DRIVERS SLRS008B - SEPTEMBER 1986 - REVISED JUNE 2002 recommended operating conditions Supply voltage VCC1 VCC2 VIH High level input voltage High-level VCC1 7 V VCC1 7 V VIL Low-level output voltage MIN MAX 4.5 7 VCC1 2.3 36 2.3 -0.3 UNIT V VCC1 7 V 1.5 V V TA Operating free-air temperature 0 70 C The algebraic convention, in which the least positive (most negative) designated minimum, is used in this data sheet for logic voltage levels. electrical characteristics, VCC1 = 5 V, VCC2 = 24 V, TA = 25C PARAMETER TEST CONDITIONS VOH High-level output voltage L293: IOH = -1 A L293D: IOH = - 0.6 A VOL Low-level output voltage L293: IOL = 1 A L293D: IOL = 0.6 A VOKH VOKL High-level output clamp voltage L293D: IOK = - 0.6 A Low-level output clamp voltage L293D: IOK = 0.6 A IIH High level input current High-level IIL Low level input current Low-level ICC1 Logic supply current A EN A EN MIN TYP VCC2-1.8 VCC2-1.4 1.2 Output supply current IO = 0 V V V 100 0.2 10 -3 -10 -2 -100 All outputs at high level 13 22 All outputs at low level 35 60 All outputs at high impedance ICC2 1.8 0.2 VI = 0 UNIT V VCC2 + 1.3 1.3 VI = 7 V IO = 0 MAX 8 24 All outputs at high level 14 24 All outputs at low level 2 6 All outputs at high impedance 2 4 A A mA mA switching characteristics, VCC1 = 5 V, VCC2 = 24 V, TA = 25C PARAMETER TEST CONDITIONS tPLH tPHL Propagation delay time, low-to-high-level output from A input tTLH tTHL Transition time, low-to-high-level output Propagation delay time, high-to-low-level output from A input CL = 30 pF, pF L293NE, L293DNE MIN See Figure 1 Transition time, high-to-low-level output TYP MAX UNIT 800 ns 400 ns 300 ns 300 ns switching characteristics, VCC1 = 5 V, VCC2 = 24 V, TA = 25C PARAMETER TEST CONDITIONS L293DWP, L293N L293DDWP, L293DN MIN TYP UNIT MAX tPLH tPHL Propagation delay time, low-to-high-level output from A input 750 ns Propagation delay time, high-to-low-level output from A input 200 ns tTLH tTHL Transition time, low-to-high-level output 100 ns 350 ns CL = 30 pF, pF See Figure 1 Transition time, high-to-low-level output POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 5 L293, L293D QUADRUPLE HALF-H DRIVERS SLRS008B - SEPTEMBER 1986 - REVISED JUNE 2002 PARAMETER MEASUREMENT INFORMATION tf tr Input 5 V 24 V Input 50% 50% 10% Pulse Generator (see Note B) VCC1 VCC2 10% 0 tw A tPLH tPHL Y 3V EN Output CL = 30 pF (see Note A) 90% 90% 50% 50% 10% tTHL TEST CIRCUIT VOLTAGE WAVEFORMS NOTES: A.
