Product details

The SN74S03D is a TTL NAND gate from the S series, supplied in bulk packaging.

This part is RoHS non-compliant. If your assembly line runs lead-free solder profiles, the SN74S03D will not pass a RoHS material declaration. It belongs on a legacy BOM where tin-lead solder is still accepted, or on a controlled exemption. Verify your end-product RoHS exemption before committing the line.

There is no NRND or last-time-buy notice.

Package and rework note

The bulk package designation typically means the part ships in tubes or loose quantities, not tape-and-reel. The leads are tin-lead plated.

Frequently asked questions

What are the differences between SN74S03D and common alternatives like 74LS03?

The SN74S03D is from the S series (Schottky TTL), which typically offers higher speed than the LS (Low-Power Schottky) series. The 74LS03 is a lower-power, slower alternative. Both are quad 2-input NAND gates with open-collector outputs, but the S series has tighter propagation delay at the cost of higher power consumption.

Can SN74S03D be used as a direct replacement for SN74S03N?

The SN74S03D and SN74S03N share the same S-series TTL NAND gate function. The suffix indicates package type: D typically denotes a SOIC surface-mount package, while N denotes a plastic DIP. They are not pin-compatible for the same footprint — verify your board's package before substituting.
