SN74AS00D

Overview

The SN74AS00D is a quadruple 2-input positive-NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the AS (Advanced Schottky) logic family, utilizing bipolar technology for high-speed performance. The device operates within a supply voltage range of 4.5V to 5.5V and supports an average propagation delay of 7ns with a drive strength of 24mA. It features push-pull outputs and is housed in a 14-SOIC package. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Ultra-high speed operation with propagation delays under 5ns
• High drive capability providing 20mA output current
• Push-pull output structure for robust signal integrity

Applications

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

Procurement Notes

Verify the specific datasheet revision, as parameters such as propagation delay may vary slightly between revisions like Rev. A. Confirm that the 14-SOIC package matches the design footprint requirements. Ensure the supply voltage constraints of 4.5V to 5.5V are strictly adhered to in the target application circuit design.

Selection Notes

Select this component when Advanced Schottky speed is required without the power consumption of standard S-series devices. It serves as a direct functional replacement for other 7400 series NAND gates where higher switching speeds and greater drive currents are necessary for system performance.

Part Context

This part is a member of the Texas Instruments 74AS logic family, designed to bridge the gap between standard TTL and faster ECL technologies. The SN74AS00D specifically provides four independent NAND functions in a single package, offering a compact solution for complex logic gating in space-constrained electronic designs.

Replacement Considerations

SN74AS00DR is the tape-and-reel variant of the same die and function.
