Product details

It takes a 4.5V to 5.5V supply and switches at 11 ns typical into a 50 pF load at 5V — fast enough for most 5V TTL bus and glue logic without worrying about signal-integrity headaches. The four independent gates each sink 8 mA or source 400 µA, which covers standard fan-out to a handful of LS or ALS loads.

Package and mounting — field-service friendly

14-DIP, 0.300 inch body width, 7.62 mm pitch — standard socketable footprint. No special tools needed: a manual IC extractor and a DIP socket let you swap this in the field without a hot-air station. If you are stocking a field kit, this is one of those parts that fits a wide range of legacy 5V logic boards.

Frequently asked questions

Is SN74ALS00AN RoHS compliant?

Yes, it is ROHS3 compliant.

SN74ALS00AN vs SN74LS00AN differences?

The ALS00 is faster (11 ns vs ~15 ns for the LS00 at 5V, 50 pF) and draws less supply current per gate. Both are 5V TTL-compatible, same pinout, same 14-DIP package. If your board already has ALS parts, stick with ALS for consistent timing; if it is all LS, the ALS00 drops in as a speed upgrade.

What are the alternatives to SN74ALS00AN?

For a through-hole 5V NAND gate, the SN74LS00AN is the slower, lower-power sibling. If you need surface-mount, the SN74ALS38BNSR offers open-collector outputs in an SO package. For a wider supply range (2V to 6V) and lower power, the SN74HC20N provides dual 4-input NAND in a 14-DIP, but the pinout differs.
