  • Logic Family: 74LS (Low-power Schottky)
  • Function: Dual D-type positive-edge-triggered flip-flop
  • Supply Voltage (VCC): 4.75V to 5.25V (nominal 5V)
  • Operating Temperature Range: 0°C to +70°C
  • Propagation Delay: Typically 20 ns (max 40 ns) at 5V
  • Power Dissipation: 20 mW per flip-flop (typical)
  • Input Current (High/Low): ±20 μA (max)
  • Output Current (High/Low): -0.4 mA / 8 mA (max)
  • Setup Time: 20 ns (min)
  • Hold Time: 5 ns (min)
  • Package: 14-pin PDIP (Plastic Dual In-line Package)
  • Features: Independent data, clock, preset, and clear inputs for each flip-flop

These specifications are based on Fairchild Semiconductor's datasheet for the DM74LS74AN.
