What are the key features of SNJ54HC42J?
- HC/UH family 4-to-10 BCD decimal decoder with 10 active-low outputs and 5.2 mA sink current per output, enabling direct LED or relay driving without buffer stages
- Military-grade 54HC logic family with full -55°C to +125°C temperature rating in a hermetically sealed ceramic DIP-16 package for defense and aerospace applications
- 50 pF load capacitance specification supports reliable operation on backplane buses in high-capacitance digital environments without signal degradation
What is SNJ54HC42J used for?
The SNJ54HC42J is used in military and aerospace digital systems for BCD-to-decimal decoding in address selection, keyboard scanning, and display multiplexing circuits that must operate reliably from -55°C to +125°C. Its 10 active-low outputs with 5.2 mA sink capability allow direct driving of discrete indicator LEDs or opto-isolators on avionics control panels and ruggedized instrumentation equipment.

Frequently Asked Questions
Which designs are a good fit for SNJ54HC42J with 50 pF?
SNJ54HC42J fits industrial, embedded, and repair-oriented electronic assemblies when the design needs 50 pF and 5.2 mA. It is a practical choice when the BOM also matches the 16-pin DIP footprint.
How should engineers check package compatibility for SNJ54HC42J?
Compare the PCB land pattern, height allowance, and assembly process against the 16-pin DIP style. The 16 pins detail is the first check before approving a replacement.
What matters when sourcing SNJ54HC42J as a replacement?
Confirm the same 50 pF, 5.2 mA, manufacturer traceability, and lifecycle status before substituting it. Buyers should also verify stock for the exact 16-pin DIP configuration.
