74AC11000NSR

Overview

The SN74AC11000NSR is a quadruple 2-input positive-NAND gate from the Texas Instruments 74AC logic series. It operates within a supply voltage range of 3 V to 5.5 V and supports low-level output currents of 24 mA and high-level output currents of -24 mA. The device features a propagation delay of 6.5 ns at 5 V with 50 pF load, ensuring rapid signal processing. Designed for surface-mount applications, it utilizes a 16-SOIC package (0.209 inch width). The component functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent 2-input NAND gates within a single integrated circuit
• Provides robust drive capability with symmetrical 24 mA output current ratings
• Delivers high-speed performance with a propagation delay of 6.5 ns under standard loading conditions

Applications

• Digital logic circuits requiring multiple NAND operations
• Signal gating and switching applications in consumer electronics
• Industrial control systems utilizing AC-series logic families

Procurement Notes

Verify the specific suffix NSR confirms the SOIC-16 surface-mount packaging variant rather than the PDIP through-hole version. Confirm RoHS compliance status and check for alternative bond wire metal specifications via recent Product Change Notices. Ensure the ordering quantity aligns with the manufacturer's standard reel size of 2,000 units for optimal procurement efficiency.

Selection Notes

Select this component when a quad 2-input NAND configuration is required in a compact surface-mount footprint. The 74AC series offers superior speed compared to legacy HC or HCT counterparts while maintaining compatible pinouts. Verify that the 3 V to 5.5 V operating voltage range matches the system power rails and that the 6.5 ns delay meets the timing requirements of the target digital interface.

Part Context

This part belongs to the Texas Instruments 74AC family, which represents advanced CMOS technology designed for high-speed digital applications. The 74AC series provides faster switching speeds and lower power consumption compared to earlier generations like 74HC. The '11000' designation specifically identifies the internal circuitry as containing four independent 2-input NAND gates, distinguishing it from other logic functions within the same package constraints.

Replacement Considerations

The SN74AC11000N serves as the direct through-hole equivalent offering identical electrical characteristics. Surface-mount alternatives within the same logic family include the SN74AC10NSR for triple 3-input configurations. Cross-reference datasheets to confirm pin compatibility and ensure voltage thresholds match the existing design parameters.
