Overview of 74LVC-series single-gate TTL chips

The 74LVC series are modern, surface-mount, single-gate versions of the classig 7400-series TTL boolean logic chips.

However, these are "multi-function" chips -- their pins can be connected to act as one of several different logic gate types.

I learned of these chips from the Mega One-8-One and I thought I'd put together an overview.

The largest package size available is SOT-23-6, which is a shame for those of us who prefer the ease of working with 0.1" DIP parts.

They are all about $0.40 each (in quantity of 1) from digikey:
