DM74ALS30ASJX

Inverter Gates Overview

The DM74ALS30ASJX is an advanced low-power Schottky (ALS) logic integrated circuit manufactured by Fairchild Semiconductor. It contains a single 8-input NAND gate housed in a 14-lead Small Outline Integrated Circuit (SOIC) package, specifically the MS-012 AA variant with a 0.209-inch width. The device operates within a supply voltage range of 4.5V to 5.5V and supports a commercial operating temperature range of 0°C to 70°C. It features a propagation delay of 11ns at 5V with 50pF load capacitance. Output drive capabilities include a maximum low-level output current of 8mA and a high-level output current of -400µA.

Inverter Gates Feature Summary

• Advanced oxide-isolated, ion-implanted Schottky TTL process for improved performance
• Functionally and pin-for-pin compatible with standard Schottky and Low Power Schottky TTL counterparts
• Switching specifications guaranteed over the full temperature and VCC range

Inverter Gates Applications

• General digital logic processing requiring 8-input NAND functionality
• Microprocessor systems utilizing ALS logic families
• Memory interface circuits compatible with standard TTL levels

Inverter Gates Procurement Notes

Verify the specific suffix ASJX against official manufacturer documentation to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the datasheet revision date to confirm switching specifications are current. Confirm the package body dimensions match the MS-012 AA JEDEC standard before integration into PCB designs.

Inverter Gates Selection Notes

Select this component when an 8-input NAND gate is required within an ALS logic family design. It serves as a direct drop-in replacement for older Schottky (S) and Low Power Schottky (LS) 7430 equivalents due to pin compatibility. Consider its 11ns propagation delay and 8mA sink capability for speed and drive requirements. Verify that the SOIC surface-mount form factor aligns with the manufacturing assembly constraints.

Inverter Gates Part Context

This part belongs to the DM74ALS series, representing Fairchild's Advanced Low-power Schottky logic line. The series bridges the performance gap between standard LS and S families, offering faster switching speeds than LS while consuming less power than S. The 'ASJX' designation indicates the specific surface-mount package and reel packaging format provided by the manufacturer.

Inverter Gates Replacement Considerations

Publicly confirmed substitute part numbers include SN74ALS30AD from Texas Instruments. Verify electrical parameters and package dimensions against the original datasheet before substitution.
