01 — About

What it does

The IC 7474 Dual D-Type Flip-Flop contains two positive-edge-triggered D flip-flops with preset and clear inputs. It is fundamental for sequential logic, data storage, counters, and state machine circuits.

Key features

  • 2 independent D-type flip-flops
  • Positive edge-triggered
  • Preset and clear inputs
  • Complementary outputs (Q and Q̄)
  • 14-pin DIP package
  • Standard TTL/CMOS compatible
  • Reliable data storage

Good to know

  • Preset and Clear are active-LOW (usually pulled HIGH)
  • Data at D input is transferred to Q on clock rising edge
  • Setup time: D must be stable before clock edge
  • Can create toggle flip-flop by connecting Q̄ to D
  • Unused flip-flop should have clock tied to valid level
