74AC11000D

Overview

The Texas Instruments 74AC11000D is a quadruple 2-input positive-NAND gate manufactured using the EPIC 1-μm CMOS process. It operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature from -40 °C to 85 °C. The device provides low-level output currents up to 24 mA and high-level output currents up to -24 mA at 5.5 V. Propagation delays are characterized at 6.5 ns maximum at 5 V, with power dissipation capacitance of 33 pF per gate.

Feature Summary

• Features center-pin VCC and GND configurations to minimize high-speed switching noise.
• Incorporates Enhanced-Performance Implanted CMOS (EPIC) technology for robust performance.
• Provides 500-mA typical latch-up immunity at elevated temperatures.

Applications

• Boolean logic implementation utilizing Y = A · B or Y = A + B functions.
• High-speed digital signal processing circuits requiring low noise profiles.
• General-purpose logic applications within industrial temperature ranges.

Procurement Notes

Verify component status as the D package variant is listed as obsolete in official documentation. Confirm availability of active production alternatives such as the DR suffix version. Ensure compliance with RoHS standards and moisture sensitivity levels during procurement planning.

Selection Notes

Select this component for designs requiring quad NAND gates with specific center-pin power distribution. Evaluate propagation delay requirements against the 6.5 ns maximum specification at 5 V. Consider the SOIC-16 package dimensions and thermal characteristics for PCB layout integration.

Part Context

This device belongs to the 74AC logic family, representing advanced CMOS technology. It serves as a standard logic gate solution for complex digital systems. The part number indicates a plastic small-outline package configuration suitable for surface-mount assembly techniques.

Replacement Considerations

The 74AC11000DR is an active production alternative offering identical electrical specifications in a tape-and-reel format. Verify pin compatibility and package dimensions before substituting the obsolete D package variant.
