SN74ALS1004D

Overview

The SN74ALS1004D is a hex inverter integrated circuit from Texas Instruments, belonging to the 74ALS logic family. It features six independent inverters housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation. Key electrical parameters include a maximum propagation delay of 7ns at 5V with 50pF load, high-level output current of 15mA, low-level output current of 24mA, and maximum static current of 3mA. It functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Contains six independent inverting channels for signal inversion applications.
• Utilizes Advanced Low-power Schottky (ALS) bipolar technology for speed and efficiency.
• Provides robust drive capability with specified high and low-level output currents.

Applications

• General-purpose digital signal inversion in logic circuits.
• Clock signal generation and conditioning systems.
• Data bus buffering and interface isolation.

Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-14 tube packaging configuration as listed in distributor catalogs. Confirm RoHS compliance status and check for any End-of-Life notifications or discontinuance alerts prior to finalizing procurement decisions. Ensure the supplier provides valid traceability documentation for the component batch.

Selection Notes

Select this component when designing systems requiring multiple inverter stages within a single package footprint. The ALS series offers a balance between power consumption and switching speed suitable for standard TTL-compatible interfaces. Consider the 14-SOIC package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Part Context

This part belongs to the Texas Instruments 74ALS series, which represents an evolution of the standard 74S logic family with improved power-delay product characteristics. The SN74ALS1004D specifically implements the hex inverter function, providing a compact solution for complex digital logic designs requiring multiple inversion points without increasing board space significantly.

Replacement Considerations

Compatible substitutes include the SN74ALS1004DG4 and SN74ALS1004DE4 variants, which maintain identical functional specifications and pinouts while potentially differing in environmental compliance certifications such as lead-free manufacturing standards.
