Inverter Gates datasheet and documents for SNJ5428J

SNJ5428J

Inverter Gates Overview

The SNJ5428J is a quadruple 2-input positive-NOR buffer manufactured by Texas Instruments. It features four independent NOR logic gates within a single package, designed for high-reliability applications requiring military-grade performance. The device operates across an extended temperature range of -55°C to 125°C and utilizes a hermetically sealed ceramic dual in-line package (CDIP) with 14 pins. This construction ensures durability in harsh environments while maintaining signal integrity through standard TTL-compatible inputs.

Extended operating temperature range from -55°C to 125°C

Inverter Gates Applications

Military aerospace systems
Harsh environment industrial control
High-reliability communication equipment

Inverter Gates Procurement Notes

Verify the specific ordering suffix against current TI documentation to confirm material type and lead finish options. Ensure compatibility with MIL-STD-1835 standards if required for your application. Confirm that the CDIP package dimensions match your existing board layout constraints before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when military-grade reliability and radiation hardness are critical requirements. The SNJ5428J is suitable for designs needing multiple NOR functions in a compact, durable form factor. Consider the extended temperature range and ceramic packaging benefits over plastic alternatives for long-term stability in extreme conditions.

Inverter Gates Part Context

This part belongs to the SN54xx series of logic devices, which are distinguished by their military-grade specifications compared to commercial SN74xx counterparts. The SNJ5428J specifically provides NOR logic functionality, differing from NAND or AND gate variants within the same family. Its ceramic construction sets it apart from standard plastic DIP packages used in consumer electronics.
