Key Features
- Single 8-input positive-NAND gate in fast Advanced Schottky (AS) logic family
- Military-grade temperature range of -55°C to +125°C for extreme environment operation
- Fast propagation delay typical under 5 ns in the AS logic family
- 20 mA output sink current (IOL) for reliable drive capability
- 14-pin ceramic DIP (GDIP) with hermetic sealing for long-term reliability
- TTL-compatible inputs for seamless integration in mixed digital systems
Applications
The SNJ54AS30J is used in military avionics computer systems, radar data processing circuits, and spacecraft logic subsystems where high-fan-in NAND operations must be executed with minimal propagation delay at extreme temperatures. It is also employed in nuclear instrumentation electronics, defense communication encryption logic, and other high-reliability systems where ceramic hermetic packaging and MIL-grade temperature ratings are non-negotiable requirements.

Frequently Asked Questions
How many inputs does the SNJ54AS30J have?
The SNJ54AS30J contains a single 8-input positive-NAND gate. All eight inputs must be logic high simultaneously for the output to assert logic low. This high fan-in configuration makes it useful for detecting when all eight conditions in a control system are simultaneously true, implementing complex combinational logic in a single package.
What temperature range does the SNJ54AS30J support?
The SNJ54AS30J is rated for the full military temperature range from -55°C to +125°C ambient. This exceeds both commercial (0°C to +70°C) and industrial (-40°C to +85°C) grades and ensures reliable high-speed logic operation in avionics, satellite electronics, and military ground vehicle systems exposed to extreme thermal conditions.
What logic family is the SNJ54AS30J part of?
The SNJ54AS30J belongs to the AS (Advanced Schottky) TTL logic family, which provides the fastest switching speeds among standard TTL families. Typical propagation delays in the AS family are under 5 ns, with full TTL input and output voltage compatibility, enabling the SNJ54AS30J to interface directly with other TTL, ALS, and FAST-family logic devices.
What package is the SNJ54AS30J available in?
The SNJ54AS30J is packaged in a 14-pin GDIP (Glass Sealed Ceramic Dual-In-Line Package), providing a hermetic seal meeting MIL-STD-883 requirements. The ceramic package offers superior resistance to moisture, chemicals, and thermal cycling compared to plastic packages, which is essential for the long service life required in military system applications.
