SN74AC11PW

Overview

The SN74AC11PW is a Texas Instruments integrated circuit belonging to the 74AC logic family. It contains three independent 3-input positive AND gates housed in a 14-TSSOP surface-mount package. The device operates within a supply voltage range of 2V to 6V, supporting low-level logic inputs from 0.9V to 1.65V and high-level inputs from 2.1V to 3.85V. It provides symmetric output drive currents of 24mA for both high and low states. Maximum propagation delay is specified at 8ns when operating at 5V with a 50pF load. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates three distinct 3-input AND logic functions within a single compact package
• Provides robust 24mA symmetrical output drive capability for reliable signal transmission
• Operates effectively across a wide 2V to 6V power supply range suitable for various digital systems

Applications

• Digital logic circuits requiring triple 3-input AND functionality
• Data acquisition systems utilizing AC series logic interfaces
• Industrial control applications operating within extended temperature ranges

Procurement Notes

Verify the specific suffix 'PWR' or 'PW' against official datasheets to confirm packaging type and reel specifications. Ensure the ordered part matches the required TSSOP-14 footprint and pinout configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly processes.

Selection Notes

Select this component when designing circuits requiring multiple 3-input AND gates in a small form factor. The AC series offers higher speed than standard 74LS devices while maintaining CMOS low power characteristics. Verify that the system voltage falls within the 2V to 6V operational window and that the 8ns propagation delay meets timing constraints.

Part Context

This part belongs to the Texas Instruments 74AC series of advanced CMOS logic devices. The 74AC family is designed to provide high-speed operation with low power consumption, serving as a modern replacement for older bipolar logic families. The SN74AC11 specifically addresses designs needing multiple AND gates without consuming excessive board space.

Replacement Considerations

SN74AC11PWR: Identical function with tape-and-reel packaging instead of tube.
