Overview
The SN7412N is a TTL logic integrated circuit manufactured by Texas Instruments, featuring three independent 3-input positive NAND gates with open-collector outputs. It operates within a supply voltage range of 4.75V to 5.25V and supports through-hole mounting in a 14-pin PDIP package. The device is designed for standard industrial temperature ranges from 0°C to 70°C.
Feature Summary
- Contains three independent 3-input NAND logic gates
- Features open-collector outputs requiring external pull-up resistors
- Compatible with standard 5V TTL logic families
Applications
- Digital logic switching circuits
- Wired-AND logic configuration implementations
- General-purpose digital signal processing
Procurement Notes
Verify the specific manufacturer source, as Consolidated Electronics also produced this part number historically. Confirm that the received component matches the Texas Instruments specification sheet regarding pinout and electrical characteristics. Ensure the package type is strictly 14-pin PDIP for mechanical compatibility.
Selection Notes
Select this component when open-collector NAND functionality is required for wired-AND applications. It is suitable for designs operating at standard 5V logic levels. Consider alternative packages if surface-mount technology is preferred over through-hole installation.
Part Context
This component belongs to the standard 74 series of logic ICs. It provides basic NAND gate functionality with open-collector outputs, distinguishing it from standard push-pull output variants. It serves as a fundamental building block for complex digital logic systems requiring specific output drive configurations.
