SN74ALS992NT

Overview

The SN74ALS992NT is a high-speed ALS logic latch manufactured by Texas Instruments. It features nine D-type transparent latches with read-back capability in a 24-pin SOIC package. The device operates on a single 5V supply, ranging from 4.5V to 5.5V. Key electrical parameters include a propagation delay of 16ns, low-level output current of 32mA, and high-level output current of -2.6mA. It functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides nine independent D-type transparent latches for data storage applications.
• Includes read-back functionality allowing direct monitoring of internal latch states.
• Utilizes Advanced Low-power Schottky (ALS) technology for high-speed operation.

Applications

• High-speed parallel data buffering systems
• Digital signal processing input/output interfaces
• Microprocessor system address and data latching

Procurement Notes

Verify the specific suffix 'NT' against official Texas Instruments documentation to confirm package type and availability status. Ensure compatibility with standard 5V logic levels and check for RoHS compliance requirements relevant to your manufacturing standards before finalizing procurement.

Selection Notes

Select this component when nine-channel latching with read-back is required in a compact surface-mount format. The ALS series offers a balance of speed and power consumption suitable for general-purpose digital logic designs requiring transparent latch behavior without complex control circuitry.

Part Context

This part belongs to the SN74ALS992 family of advanced low-power Schottky logic devices. It is designed as a direct replacement for older TTL logic families while offering improved switching speeds and lower power dissipation characteristics typical of the ALS series architecture.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives if the SN74ALS992NT is unavailable. Verify that any substitute maintains the same 24-pin SOIC footprint and logical functionality to ensure seamless integration into existing PCB layouts.
