SN74ACT11PW

Overview

The SN74ACT11PW is a triple 3-input positive-AND gate manufactured by Texas Instruments. It belongs to the 74ACT logic series and utilizes CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features low quiescent current, typically 2 µA. The propagation delay is specified at 9.5 ns when operating at 5 V with a 50 pF load. Output drive capability provides 24 mA for both high and low states. Logic levels define a minimum high-level input voltage of 2 V and a maximum low-level input voltage of 0.8 V. The component is housed in a 14-TSSOP package.

Feature Summary

• Integrates three independent 3-input AND gates within a single surface-mount package.
• Ensures compatibility with standard TTL logic families through compatible input threshold voltages.
• Delivers robust output drive strength suitable for driving multiple loads or transmission lines.

Applications

• Digital logic circuits requiring multi-input AND functionality
• Microprocessor-based systems utilizing 5 V logic interfaces
• General-purpose combinatorial logic design

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the manufacturer's datasheet.

Selection Notes

Select this component when designing with 5 V CMOS logic that requires direct interfacing with TTL signals. The ACT series offers faster switching speeds compared to standard 74HC devices while maintaining low power consumption. Consider the TSSOP-14 footprint constraints and thermal management requirements for dense PCB layouts.

Part Context

This part is part of the broader 74ACT family of high-speed CMOS logic devices. It shares functional similarities with other 74ACT gates but is distinct from the 74AC series which supports wider voltage ranges. The PW suffix specifically denotes the plastic small-outline thin-profile package variant used for surface-mount applications.

Replacement Considerations

SN74ACT11DR serves as a reel-packaged alternative from the same manufacturer. SN74ACT11PWR is available in a TSSOP-14 package. Verify pin compatibility and electrical parameters before substituting with generic equivalents.
