SN74ACT11NSR

Overview

The SN74ACT11NSR is a logic gate component manufactured by Texas Instruments, belonging to the SN74ACT series. It contains three independent 3-input AND gates within a single package. The device operates on a supply voltage (VCC) ranging from 4.5 V to 5.5 V and features inputs that are TTL-voltage compatible. It utilizes an NS (Small Outline Package) form factor with tape and reel packaging for automated assembly. Electrical characteristics include a maximum propagation delay of 10.5 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA.

Feature Summary

• Contains three independent 3-input AND gates performing Boolean function Y = A • B • C
• TTL-voltage compatible inputs accept voltages up to 5.5 V
• High-speed operation with a maximum propagation delay of 10.5 ns at 5 V
• Robust output drive capability with ±24 mA high and low-level output currents

Applications

• Digital logic circuits requiring triple 3-input AND functionality
• Data acquisition systems utilizing TTL-compatible interfaces
• Industrial control applications operating within standard temperature ranges

Procurement Notes

Verify the specific ordering suffix 'SR' corresponds to the tape and reel packaging configuration as documented in the manufacturer's ordering information table. Confirm the package type matches the NS designation for small outline packages. Ensure the procurement specifications align with the recommended operating conditions, specifically the 4.5 V to 5.5 V supply voltage range and the industrial temperature limits defined for the SN74 variant.

Selection Notes

Select this component when a design requires multiple 3-input AND gates in a compact surface-mount format. The ACT series offers faster switching speeds compared to older AC or HC families while maintaining CMOS power efficiency. Consider the NS package dimensions if board space is constrained relative to through-hole alternatives like the N package. Verify input compatibility with the driving logic levels to ensure proper signal integrity across the operating temperature range.

Part Context

This part belongs to the SN74ACT family of high-speed CMOS logic devices produced by Texas Instruments. The '11' designation identifies the specific logic function as a triple 3-input AND gate. The 'N' indicates the plastic dual-in-line or small outline package style, while 'S' denotes the shrink version, and 'R' signifies tape and reel packaging. This family bridges the performance gap between standard TTL and advanced CMOS technologies.

Replacement Considerations

SN74ACT11DR: Same logic function and electrical specifications but packaged in SOIC-14 instead of NSOP-14.
