74C

74C is a designation used in the electronics industry to identify a subset of integrated circuits in the 7400-series of digital logic devices. The 7400 family was developed in the mid-20th century and became a broad collection of logic components, including gates, latches, and flip-flops, used in countless digital designs. The suffix ā€œCā€ is a manufacturer-specific marker that, in different lines, indicated a particular process, family variant, or performance tier. As a result, 74C parts can span a range of device types from basic gates to more complex logic blocks, depending on the manufacturer.

Devices labeled 74C are typically general-purpose logic parts intended as cost-effective building blocks for digital circuits.

In modern practice, many designers migrate to newer 74xx families such as 74HC/74HCT and 74AC/74ACT, which offer
