  • 603-10004: 74LVC244A Octal Buffer/Line Driver
Product ID: 603-10004
In Stock: 62


The 74LVC244A is an octal buffer which can be used to buffer signals to or from microcontrollers or other devices. This device accepts up to 5V on the input allowing 5V interface to 3.3V devices. The 20 pin DIP package allows for easy breadboard prototyping and the package includes 8 buffered drivers that can source or sink 24 mA. Outputs are tristate capable.

Key Features:

  • Buffers 3.3V & 5V signals w/3.3V output making 5V signals compatible with 3.3V inputs
  • Can operate down to 1.65V
  • Tri-state outputs

Application Ideas:

  • Connect 5V sensors to Propeller chip
  • Connect BASIC Stamps to 3.3V sensors
  • Communication buffer between BASIC Stamps and Propeller


  • Voltage requirements: 1.65-3.6 VDC
  • Current requirements: Current depends on load
  • Communication: Parallel interface 8x buffer/driver enabled as 2 groups of 4
  • Package: DIP-20 (0.300")
  • Operating temp range: -40 to +185°F (-40 to +85°C)
