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.
