SN74ACT32N-NG

Overview

The SN74ACT32N-NG is a quad 2-input positive-OR gate from the Texas Instruments SN74ACT series. It operates within a supply voltage range of 4.5V to 5.5V and features low static current consumption, with a maximum of 2uA. The device utilizes a 14-pin SOIC package and provides four independent logic circuits. It supports TTL-compatible inputs and CMOS outputs, ensuring compatibility with standard digital logic systems while maintaining high-speed performance characteristics typical of the ACT family.

Feature Summary

• Contains four independent 2-input OR gates for complex logic implementation
• Operates on a single 5V power supply with wide noise immunity
• Features low static power dissipation suitable for battery-powered applications

Applications

• Digital signal processing logic circuits
• Microcontroller input interface expansion
• General-purpose logic gating in industrial control systems

Procurement Notes

Verify the specific suffix 'NG' against official Texas Instruments documentation to confirm exact packaging or temperature grade variations. Ensure the component matches the standard SN74ACT32 pinout and electrical specifications before integration. Cross-reference datasheet revisions to confirm compliance with current RoHS standards and lead-free manufacturing processes required by your assembly line.

Selection Notes

Select this component when designing 5V logic systems requiring multiple OR functions in a compact surface-mount or through-hole form factor. It serves as a direct replacement for older 74LS32 equivalents where lower power consumption and higher speed are prioritized. Consider the 14-pin package constraints and ensure adequate thermal management if operating near maximum temperature limits.

Part Context

This part belongs to the SN74ACT logic family, which bridges the performance gap between older LS-TTL and newer HC technologies. The ACT series offers faster propagation delays and lower power than LS counterparts while maintaining compatible input thresholds. This specific model integrates four OR gates, providing essential logical disjunction capabilities for digital circuit design without requiring external components.

Replacement Considerations

Compatible substitutes include the SN74ACT32DR and SN74ACT32PWR from Texas Instruments, provided the package type (SOIC vs TSSOP) matches the PCB footprint. Verify that alternative manufacturers offer equivalent 4.5V-5.5V operating ranges and identical pin configurations to ensure functional interchangeability.
