What are the key features of SN54HC259J?
- 8-channel 1-of-8 demultiplexer followed by a latch for addressable data storage across 8 outputs
- High-reliability 16-pin ceramic DIP (CDIP) package rated for -55°C to +125°C military temperature range
- HC/UH CMOS family operation from 2 V to 6 V supply with 50 pF load capacitance rating
What is SN54HC259J used for?
The SN54HC259J suits military-grade control systems where addressable latching of 8 discrete outputs from a 3-bit address bus is required. It is used in ruggedized industrial I/O expansion boards where the ceramic package provides superior thermal and mechanical stability. Legacy military avionics and space-rated systems benefit from its CDIP package and extended -55°C to +125°C temperature range.

Frequently Asked Questions
What is the operating temperature range of the SN54HC259J and why is it suited for military designs?
The SN54HC259J is rated from -55°C to +125°C, meeting the full military temperature specification. Its 16-pin ceramic DIP package provides hermeticity and mechanical robustness that plastic packages cannot match, making it a standard choice for mil-spec avionics and ground-based control electronics requiring 8-channel latched outputs.
How does the SN54HC259J differ from a standard 8-bit D-type latch in addressing behavior?
Unlike a parallel-load latch, the SN54HC259J uses a 3-bit address (A0, A1, A2) to select 1 of 8 output channels, acting as a 1-of-8 demultiplexer with latched outputs. Each addressed channel stores a single bit, enabling sequential loading of all 8 outputs over 8 write cycles with only 1 data input line.
What supply voltage and load capacitance does the SN54HC259J support in HC CMOS logic systems?
The SN54HC259J operates from a 2 V to 6 V supply voltage and is characterized at 50 pF load capacitance per output. The HC family guarantees a maximum output low current of 5.2 mA, allowing direct drive of standard CMOS and TTL-compatible inputs without external buffers in most 3.3 V and 5 V digital systems.
