SN74ACT32NS

Overview

The SN74ACT32NS is a quad 2-input positive-OR gate from the Texas Instruments SN74ACT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low static power consumption with a maximum quiescent current of 2 µA. The device provides high noise immunity and includes clamp diodes on each input for transient protection. It utilizes a 14-pin plastic small-outline (SOIC) package, supporting surface-mount or through-hole integration depending on specific variant configurations.

Feature Summary

• Contains four independent 2-input OR logic gates
• Operates at standard 5-V supply voltage
• Features low static power dissipation
• Includes input clamp diodes for transient protection

Applications

• General-purpose digital logic circuits
• Signal routing and selection systems
• Industrial control logic interfaces

Procurement Notes

Verify the exact suffix against the manufacturer's official documentation to confirm pinout compatibility and package type. Ensure the selected variant matches the required operating temperature range and electrical specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when designing 5-V logic systems requiring multiple OR functions in a single package. Consider the ACT series characteristics for improved speed over older LS equivalents while maintaining CMOS low-power benefits. Verify that the chosen package style aligns with the PCB layout constraints and assembly capabilities.

Part Context

This part belongs to the SN74ACT family, which combines the high-speed performance of bipolar logic with the low power consumption of CMOS technology. The SN74ACT32 specifically implements OR logic functionality, serving as a fundamental building block for complex digital signal processing and control applications within standard 5-V logic environments.

Replacement Considerations

Compatible substitutes include the SN74ACT32DR and SN74ACT32DRE4. Verify pin compatibility and electrical parameters before substitution.
