7400 series is an extended family of digital integrated circuits. Chips in this series include a variety of discrete logic chips chips such as and gates and or gates as well as registers, decoders, and RAM units.
While the original series was designed as TTL logic chips, over the years, a large number of sub-families have been introduced. Generally speaking, parts from the same subfamily can be used freely with other parts from the same subfamily. However, in many cases not with parts from other subfamilies. This is because voltage and current configurations for ICs from the same subfamily are designed so they can be connected without requiring additional work.

Example[edit]
Chip is labeled DM74LS221N:
- DM - prefix - made by Fairchild or National Semiconductor, but given the F logo, we can determine it's Fairchild.
- 74 - series - commercial grade chip
- LS - techno - Low-power Schottky.
- 221 - device - Dual non-retriggerable monostable multivibrator with reset
- N - package - standard plastic DIP
