SN74ALS819NT

Shift Registers Overview

The SN74ALS819NT is an 8-bit pipeline register manufactured by Texas Instruments, belonging to the ALS logic series. It utilizes a TTL-compatible interface and is housed in a 24-pin PDIP package for through-hole mounting. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a commercial temperature range from 0°C to +70°C. Designed for high-speed digital applications, it features low propagation delay characteristics typical of the Advanced Low-power Schottky family, ensuring efficient data storage and transfer in complex logic circuits.

Shift Registers Feature Summary

• Provides 8-bit parallel data storage capability within a single integrated circuit
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption
• Features TTL-compatible input and output levels for broad system integration
• Offers pipeline register functionality to manage data flow timing in sequential logic

Shift Registers Applications

• High-speed data buffering in digital communication systems
• Parallel-to-serial conversion interfaces requiring precise timing control
• Memory address latching in microprocessor-based architectures
• Pipeline stage isolation in high-frequency signal processing chains

Shift Registers Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-24 through-hole package variant when sourcing. Confirm the 'T' indicates tape-and-reel packaging if bulk handling is required. Ensure compatibility with 5V logic families. Check for RoHS compliance status as per current manufacturer documentation. Validate that the ALS series specifications meet your system's power and speed requirements before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit parallel register with TTL compatibility is required. The ALS series offers a balance of speed and power dissipation suitable for general-purpose digital logic. Consider the PDIP-24 package for prototyping or through-hole manufacturing processes. Evaluate the propagation delay against your system clock frequency to ensure timing margins are sufficient for reliable operation in your specific application environment.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74ALSxx series, which represents Advanced Low-power Schottky logic. This family was designed to improve upon standard 74LS performance while maintaining pin compatibility. The SN74ALS819 specifically addresses the need for multi-bit storage elements in systems requiring fast switching speeds and reduced power consumption compared to earlier logic families.

Shift Registers Replacement Considerations

Direct substitutes include other SN74ALS819 variants with different packaging options such as SOIC or PLCC. Cross-reference with SN74AS819 for potentially higher speed performance if power constraints allow. Verify pinout compatibility when substituting with generic 8-bit latch ICs from other manufacturers.
