SN74ACT32DG4

Overview

The SN74ACT32DG4 is a quadruple 2-input positive-OR gate from the Texas Instruments 74ACT logic family. 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 supports an operating temperature range up to 85°C. Designed for high-speed CMOS applications, it provides robust output drive capabilities suitable for standard digital logic interfacing requirements.

Feature Summary

• Contains four independent 2-input OR gates in a single package
• Operates on a standard 5V supply rail (4.5V to 5.5V)
• Features low static power consumption typical of ACT series

Applications

• Digital signal processing circuits requiring logical OR operations
• Address decoding systems in microprocessor-based designs
• Control logic interfaces for peripheral devices

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the active status with the latest Texas Instruments product selection guide to avoid obsolete components.

Selection Notes

Select this component when a quad 2-input OR function is required in a 5V CMOS environment. Compare propagation delay specifications against system timing constraints. Evaluate the SOIC package dimensions for thermal management and board space limitations relative to alternative packages like TSSOP or DIP.

Part Context

This part belongs to the SN74ACT32 series, which offers higher speed performance compared to standard 74LS logic while maintaining compatible pinouts. The ACT series is designed for applications requiring faster switching speeds and lower power dissipation than older bipolar technologies, fitting into modern digital design architectures.

Replacement Considerations

Direct replacements include SN74ACT32D and SN74ACT32DRG4. Verify that substitute parts maintain identical logic functionality and package dimensions before integration.
