SN74ALS996NT

SN74ALS996NT Description

The SN74ALS996NT is an 8-bit transparent D-type latch from Texas Instruments' 74ALS series, designed for high-speed digital data storage and transfer applications. Housed in a 24-pin DIP (Dual Inline Package), this through-hole-mount IC operates within a 4.5V to 5.5V supply range, making it compatible with standard TTL logic levels. With a propagation delay of just 5ns, it ensures rapid data handling, while its 400µA high-level and 8mA low-level output current capabilities provide robust drive strength for connected loads. The device is ROHS3 compliant and rated for industrial temperatures (0°C to 70°C), ensuring reliability in varied environments.

SN74ALS996NT Features

• High-Speed Operation: 5ns propagation delay for efficient real-time data processing.
• Wide Voltage Compatibility: 4.5V–5.5V supply range aligns with TTL standards.
• Strong Output Drive: 8mA sink current supports direct interfacing with multiple loads.
• Transparent Latching: Allows continuous data flow when enabled, ideal for buffering.
• Industrial Durability: Operates across 0°C to 70°C, suitable for harsh conditions.
• Compliance: ROHS3, REACH Unaffected, and EAR99 classified for global use.

SN74ALS996NT Applications

• Data Buffering: Acts as an intermediary in microprocessor/memory systems to stabilize data buses.
• Register Storage: Used in shift registers or temporary storage for arithmetic logic units (ALUs).
• Bus Interface: Facilitates signal isolation in 8-bit parallel communication systems.
• Industrial Control Systems: Reliable performance in PLCs and automation hardware.
• Legacy Equipment Maintenance: Ideal for repairing/upgrading older TTL-based systems due to its DIP packaging and backward compatibility.

Conclusion of SN74ALS996NT

The SN74ALS996NT excels in high-speed, low-power data latching with its 8-bit transparent design and robust output drive. While obsolete, its through-hole package and TTL compatibility make it valuable for legacy systems, industrial controls, and educational prototyping. Engineers seeking a reliable, fast-response latch for 5V logic systems will find this IC a pragmatic choice, despite newer alternatives. Its balance of speed, drive strength, and durability ensures relevance in niche applications.
