Rated for -40°C to 125°C, the SN74AHC08DR is specified for industrial and automotive environments — outdoor telecom cabinets, under-hood engine control modules, and factory-floor PLC I/O cards. The 14-SOIC package is a standard footprint; verify clearance if conformal coating is planned, as the 0.154" body width leaves limited room between adjacent pins.
TI lists the SN74AHC08DR as Active and ROHS3 compliant.
Yes, the SN74AHC08DR is ROHS3 compliant per TI's lifecycle record.
Maximum propagation delay is 7.9 ns at 5V with a 50 pF load.
The SN74LV08ADR is a functional equivalent from TI's 74LV series with the same quad 2-input AND gate topology, 14-SOIC package, and 7.9 ns propagation delay at 5V, but operates down to 2V and has 12 mA output drive versus 8 mA. Verify pin compatibility and timing before substituting.
