Flip Flops

octal D flip-flopLS TTLactive-low clear20-pin SOIC

SN74LS273DWR is an eight-bit LS-TTL register IC containing positive-edge-triggered D flip-flops with a shared active-low clear input.

Best for

  • Parallel data storage
  • Buffer and storage registers
  • Shift-register and pattern-generation logic

Avoid if

  • The design requires asynchronous preset inputs or three-state outputs
  • The circuit cannot support 5 V LS-TTL operation

Check before use

  • Clear pulse width and inactive-state setup time
  • Input and output voltage/current limits
  • Package drawing and board footprint
