8-input NAND in 14-SOIC — propagation delay sets the timing margin
The SN74ALS30AD is a single 8-input NAND gate from Texas Instruments' 74ALS family. The output can source 400 µA and sink 8 mA, enough to drive one or two standard TTL loads or a light LED indicator directly.
Active lifecycle and compliance
It is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive for lead-free soldering processes.
Where the part fits in the 74ALS lineup
The 74ALS series is a low-power Schottky logic family that balances speed and power dissipation — the 8-input NAND function is used in address decoding, data multiplexing, and wide-AND gating in processor and memory interface circuits.
