DM74ALS04BM

DM74ALS04BM Description

The DM74ALS04BM from Fairchild Semiconductor (now onsemi) is a hex inverter IC belonging to the 74ALS series, designed for high-speed digital logic applications. Packaged in a 14-pin SOIC (Surface Mount) and supplied in tube packaging, this device operates within a 4.5V to 5.5V range, making it ideal for 5V TTL-compatible systems. With a maximum propagation delay of 11ns at 5V and 50pF load, it ensures efficient signal inversion while maintaining low power consumption. Though marked as obsolete, it remains relevant in legacy systems due to its ROHS3 compliance and reliable performance in industrial temperature ranges (0°C to 70°C).
