That is enough to drive one or two standard TTL loads, or a CMOS input with a pull-up. Do not plan on driving an LED directly or fanning out to more than about ten 74LS inputs — the low-side current is the limiting factor. If you need more drive, look at the 74ALS or 74F variants which offer higher output current. For a simple gate-to-gate connection, this drive level is adequate and keeps power dissipation low. ## Lifecycle — active, no LTB pressure The SN74LS00NS carries an active product status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For a drop-in replacement in an existing 5 V TTL board, this is the correct part.","metaTitle":"SN74LS00NS 74LS Quad 2-Input NAND Gate","metaDescription":"Texas Instruments SN74LS00NS quad 2-input NAND gate in 14-SOIC. 4.75-5.25 V supply, 15 ns delay at 5 V/15 pF.
