Overview

The ’FCT574 is an octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition.

  • Inputs and outputs on opposite sides of package allowing easy interface with microprocessors
  • Useful as input or output port for microprocessors
  • Functionally identical to ’FCT374
  • TRI-STATE outputs for bus-oriented applications
  • Output sink capability of 32 mA, source capability of 12 mA
  • TTL input and output level compatible
  • CMOS power consumption
