Both 5400 and 7400 IC's were developed by TEXAS instruments only. The difference between the 5400 and the 7400 series is that the 5400 series devices operate over the military temperature range of -55°C to 125°C, and the less expensive 7400 series devices need only operate over the commercial temperature range of 0°C to 70°C. In short, 5400 ICs are of military grade and 7400 ICs are of commercial grade.
