SN74AS00DE4

Overview

The SN74AS00DE4 is a quadruple 2-input positive-NAND gate from the Texas Instruments AS logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a SOIC-14 package. Key electrical parameters include a maximum propagation delay of 4.5 ns, a low-level output current of 400 uA, and a high-level output current of -8 mA. The device supports surface-mount installation and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Ultra-high-speed operation with propagation delays under 5 ns
• Quadruple 2-input NAND logic functionality
• Push-pull output configuration for robust signal driving

Applications

• High-speed digital logic circuits
• Data acquisition systems
• Telecommunications equipment

Procurement Notes

Verify the specific DE4 suffix against official Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Ensure the SOIC-14 package dimensions match your PCB footprint requirements. Confirm that the 4.5 V to 5.5 V supply voltage range aligns with your system's power rails before finalizing procurement.

Selection Notes

Select this component when ultra-high speed is critical, as it offers significantly faster performance than standard LS or HC families. The AS series provides a balance of speed and drive capability suitable for demanding digital applications. Consider the SOIC-14 package if surface-mount technology is required for compact board designs.

Part Context

This part belongs to the SN74AS00 family of quadruple 2-input NAND gates. The 'AS' designation indicates the Advanced Schottky TTL technology, which prioritizes high-speed switching over power efficiency compared to other 74-series variants. The DE4 suffix typically denotes a specific tape-and-reel packaging format compliant with environmental standards.
