L293D Quad Half-H Drivers

  • 603-00019: L293D Quad Half-H Drivers
In Stock: 43
Product ID 603-00019


The L293D is designed to provide bi-directional drive currents of up to 600mA at voltages from 4.5 V to 36 V. Unlike the ULN2803 the L293D can source or sink current and is also known as a push-pull driver. Like the ULN2803 the L293D can drive inductive loads such as relays, solenoids and stepper-motors in positive-supply applications. Inputs are TTL compatible. See the manufacturer datasheet for additional information.

Compatible with our Professional Development Board (#28138), Propeller Professional Development Board (#32111) and Propeller Education Kits (#32305 / #32306).

Key Features:

  • Output clamp diodes for inductive transient suppression
  • Internal ESD protection
  • Thermal shutdown
  • High-noise-immunity inputs

Application Ideas:

  • Stepper motor control
  • DC motor with direction control
  • High-current Lamp/LED driver

Note: Current ratings are affected by thermal considerations (heat sink).


  • Voltage requirements: 4.5-36 VDC
  • Current requirements: Current depends on load
  • Communication: Four single inputs
  • Package: DIP-16 (0.300")
  • Operating temp range: +32 to +158 °F (0 to +70 °C)
