SN54AS08J Description

The SN54AS08J from Texas Instruments is a high-performance quad 2-input AND gate belonging to the 54AS series, designed for robust operation in industrial and military environments. Housed in a 14-pin CDIP (Ceramic Dual In-Line Package), this through-hole-mounted IC operates over a 4.5V to 5.5V supply range, making it ideal for 5V TTL logic systems. With a maximum propagation delay of 6.5ns at 5V and 50pF load, it ensures fast signal processing, while its ROHS3 compliance and REACH unaffected status underscore its environmental and regulatory suitability.

SN54AS08J Features

• Logic Type: Quad 2-input AND gate with 4 independent circuits in a single package.
• High-Speed Performance: 6.5ns propagation delay at 5V, enabling efficient timing-critical applications.
• Wide Voltage Range: Operates from 4.5V to 5.5V, ensuring compatibility with standard TTL levels.
• Robust Input/Output: Input thresholds of 0.8V (Low) and 2V (High) with 2mA (High) and 20mA (Low) output drive, supporting strong noise immunity.
• Durable Packaging: Ceramic DIP (CDIP) offers superior thermal and mechanical reliability for harsh environments.
• Extended Reliability: Military-grade (54-series) construction ensures operation across extreme temperatures and conditions.

SN54AS08J Applications

• Digital Logic Systems: Used in arithmetic logic units (ALUs), multiplexers, and data routing circuits due to its fast switching.
• Industrial Control: Ideal for PLC interfaces, motor control logic, and sensor signal conditioning where noise immunity is critical.
• Aerospace/Defense: Suited for avionics and ruggedized systems thanks to its wide temperature tolerance and ceramic packaging.
• Legacy Equipment Maintenance: Perfect for retrofitting older 5V TTL systems without redesigns.

Conclusion of SN54AS08J

The SN54AS08J stands out as a high-speed, reliable AND gate solution for demanding applications. Its military-grade durability, low propagation delay, and strong drive capability make it superior to commercial-grade alternatives. Whether in industrial automation, defense systems, or legacy upgrades, this IC delivers precision, speed, and long-term reliability, backed by Texas Instruments' proven quality.
