ULN2066B - 50V - 1.5A quad Darlington switches

Download the ULN2066B datasheet PDF. This datasheet also covers the ULN2064B variant, as both devices belong to the same 50v - 1.5a quad darlington switches family and are provided as variant models within a single manufacturer datasheet.

General Description

Designed to interface logic to a wide variety of high current, high voltage loads, these devices each contain four NPN Darlington switches delivering up to 1.5 A with a specified minimum breakdown of 50 V and a sustaining voltage of 35 V measured at 100 mA.

Key Features

  • Output current to 1.5 A for each Darlington.
  • Minimum breakdown 50 V.
  • Sustaining voltage at least 35 V.
  • Integral suppression diodes (ULN2064B, ULN2066B and ULN2068B.
  • Isolated Darlington pinout (ULN2074B).
  • Versions compatible with all popular logic families.
