Product details

Single 8-input NAND gate in 14-SOIC — what this part is

The Texas Instruments SN74LS30DR is a single 8-input NAND gate from the 74LS low-power Schottky family. It performs the logical NAND function on eight inputs and outputs a single result. The part is supplied in a 14-SOIC surface-mount package (0.154" body width) and operates from a 4.75 V to 5.25 V supply. It is rated for the commercial temperature range of 0°C to 70°C, making it suitable for indoor electronic equipment, office appliances, and general-purpose PCB logic where ambient temperature stays within that band.

20 ns propagation delay — timing margin for the bus

The maximum propagation delay is 20 ns at 5 V into a 15 pF load.

Frequently asked questions

Is SN74LS30DR a lead-free device?

Yes, the SN74LS30DR is ROHS3 compliant, meaning it meets the Restriction of Hazardous Substances directive for lead and other substances.

What are the equivalents or cross references for SN74LS30DR?

The SN74LS30DR is a single 8-input NAND gate. A functional equivalent in a different logic family would be the SN74ALS38BNSR (quad 2-input NAND with open collector) or the SN74F00DR (quad 2-input NAND, faster at 5 ns). Neither is a direct pin-for-pin replacement; the 8-input topology is specific. For a same-function 8-input NAND, stick with the 74LS30 or its 74ALS variant.
