Substitute Part Grouping Explanation

Substitution of the DM74ALS1004N is determined by strict equivalence across the following parameters:

  • Logic type and circuit configuration (6-channel inverter, 1 input per channel)
  • Electrical specifications (supply voltage 4.5V ~ 5.5V, output current 15mA/24mA, propagation delay 7ns @ 5V/50pF)
  • Input logic thresholds (0.8V low, 2V high)
  • Operating temperature range (0°C ~ 70°C)
  • Physical package compatibility (14-DIP through-hole mounting)
  • Series classification (74ALS)

The SN74ALS1004N from Texas Instruments meets all these criteria and is classified as an active product, providing long-term availability and supply continuity.
