UDN2559 - PROTECTED QUAD POWER DRIVER

General Description

Providing improved output current limiting, the UDK, UDN, and UDQ2559B, EB, and LB quad power drivers combine AND logic gates and high-current bipolar outputs with complete output protection.

Each of the four outputs sink 700 mA in the on state.

Key Features

  • 700 mA output current per channel.
  • Independent overcurrent protection for each driver.
  • Thermal protection for device and each driver.
  • Low output-saturation voltage.
  • Integral output flyback diodes.
  • TTL and 5 V CMOS-compatible inputs Packages: 16-pin DIP with exposed thermal tabs (B package) 28-pin PLCC (Package EB) Not to scale 16-pin SOICW with internally fused pins (LB package).
