SN74ALS996-1NT

Overview

The SN74ALS996-1NT is an octal D-type edge-triggered read-back latch from the Texas Instruments ALS logic family. It features a 24-pin PDIP package and operates within a supply voltage range of 4.5 V to 5.5 V. The device includes eight data inputs, eight outputs, and dedicated read-back inputs for status monitoring. Key electrical specifications include a propagation delay of 28 ns, a low-level output current of 32 mA, and a high-level output current of -2.6 mA. It functions reliably across an operating temperature range of 0°C to +70°C with a typical quiescent current of 85 mA.

Feature Summary

• Provides edge-triggered latching functionality with simultaneous read-back capability for input state verification.
• Features configurable tri-state outputs suitable for bus-oriented systems requiring controlled signal isolation.
• Utilizes Advanced Low-Power Schottky (ALS) technology to balance speed and power consumption.

Applications

• High-speed data acquisition systems requiring precise timing control
• Bus interface circuits in industrial automation controllers
• Memory buffer stages in embedded computing architectures

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and pin alignment against datasheet mechanical drawings. Validate lot traceability and storage conditions to ensure performance reliability in critical applications.

Selection Notes

Select this component when octal latching with read-back feedback is required in ALS-compatible designs. Ensure system voltage remains within 4.5 V to 5.5 V limits. Consider thermal management for continuous operation near maximum ambient temperature ratings.

Part Context

Part of the SN74ALS996 series offering octal D-type latching with read-back. Manufactured by Texas Instruments using ALS technology for improved speed-power product compared to standard 74LS equivalents. Designed for robust digital logic applications requiring high fan-out and fast switching characteristics.

Replacement Considerations

SN74ALS996DW is a direct pin-compatible alternative in SOIC-24 packaging. Verify functional equivalence and package dimensions before substitution.
