At a glance

• Type: Quad NAND
• Supply voltage (V_CC): 4.75-5.25V
• Package: DIP-14
• Manufacturer: Texas Instruments

Typical applications

Supply headroom of 4.75-5.25V determines the usable output swing; allow for the device's output saturation limits when planning signal levels.

Choosing a replacement for the SN74LS00

A drop-in substitute for the SN74LS00 should match its polarity and offer a compatible supply range (4.75-5.25V).

Mechanically, check the replacement against the DIP-14 footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.

Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.

Frequently asked questions

What is the SN74LS00?
