SN74ALS00ADE4

Overview

The SN74ALS00ADE4 is a quad 2-input positive-NAND gate from the Texas Instruments ALS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features an SOIC-14 surface-mount package. Key electrical parameters include a propagation delay of 11 ns, a low-level output current of 8 mA, and a high-level output current of -400 uA. The device supports a commercial operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input NAND gates in a single integrated circuit
• Utilizes Advanced Low-power Schottky (ALS) technology for optimized speed and power consumption
• Provides push-pull outputs capable of driving standard TTL loads

Applications

• General-purpose digital logic signal processing
• Boolean logic implementation in control circuits
• Data routing and switching applications

Procurement Notes

Verify the EOL status with the manufacturer before finalizing designs. Confirm that the specific suffix 'E4' denotes lead-free compliance without altering functional specifications. Ensure the SOIC-14 footprint matches the target PCB layout requirements.

Selection Notes

Select this component when requiring fast switching speeds with lower power dissipation than standard LS series devices. The ALS family offers improved performance while maintaining pin compatibility with legacy 74LS designs. Verify thermal management needs for dense surface-mount assemblies.

Part Context

This part belongs to the SN74ALS00A series of quadruple 2-input NAND gates. The 'E4' suffix indicates environmental compliance, specifically lead-free manufacturing. It serves as a direct replacement for older non-compliant variants within the same logical function family.

Replacement Considerations

SN74ALS00AD is the primary equivalent variant differing only in packaging or compliance details.
