Overview
The SN74H22N is a dual four-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the HC logic series and utilizes CMOS technology for low power consumption. The device operates within a supply voltage range of 2V to 6V and supports through-hole installation in a 14-pin PDIP package. It functions as a standard logic gate with open-collector outputs, suitable for general digital applications across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual four-input NAND gate configuration
- Open-collector output structure
- HC logic series compatibility
Applications
- Digital logic circuit design
- Signal processing interfaces
- General-purpose switching applications
Procurement Notes
Verify the specific manufacturer source when ordering, as multiple entities may distribute this component. Confirm the package type is PDIP-14 and the logic family is HC. Ensure the supplier provides valid traceability documentation. Check for any specific handling requirements related to static-sensitive devices during storage and transport.
Selection Notes
Select this component when a dual four-input NAND function with open-collector outputs is required. The HC series offers compatibility with standard TTL levels while maintaining lower power consumption than older LS variants. Consider the PDIP package for prototyping or applications requiring through-hole mounting on printed circuit boards.
Part Context
This part is part of the Texas Instruments SN74xx logic family, specifically the HC (High-speed CMOS) sub-family. It serves as a fundamental building block for complex digital systems, providing logical inversion and combination capabilities. The open-collector feature allows for wired-AND connections and level shifting between different voltage domains.
Replacement Considerations
Compatible substitutes include other manufacturers' SN74H22N equivalents or generic 74HCT22N variants if TTL-compatible inputs are needed. Verify pinout compatibility and electrical characteristics such as propagation delay and output current before substitution.
