SN74F32DR

Overview

The SN74F32DR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It belongs to the 74F series of Schottky TTL logic devices, designed for high-speed digital applications. The component operates within a standard supply voltage range of 4.5V to 5.5V and features a 14-pin Small Outline Integrated Circuit (SOIC) package with a lead pitch of 0.1 inches. It supports an operating temperature range from 0°C to 70°C. The device provides four independent OR gates in a single package, offering propagation delays typical of the F series for efficient signal processing.

Feature Summary

• Contains four independent 2-input OR logic functions
• Utilizes Schottky TTL technology for high-speed switching performance
• Compatible with standard 5V logic systems

Applications

• Digital logic circuit design
• Signal routing and selection
• Computer peripheral interfaces

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and environmental compliance. Ensure the ordering part number matches the required pin configuration and thermal characteristics. Cross-reference datasheets for any recent manufacturing changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when high-speed OR logic is required within standard 5V TTL environments. Compare propagation delay specifications against system timing requirements. Consider alternative packages if board space constraints differ from the SOIC footprint. Verify input/output voltage levels match the connected logic family standards.

Part Context

This device is part of the broader 74F series, known for improved speed over standard 74LS counterparts. It serves as a fundamental building block in digital electronics for implementing logical disjunction operations. The DR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Check for direct equivalents such as SN74F32N for through-hole variants or SN74F32NSR for similar surface-mount options. Verify functional compatibility with other 74F series OR gates from different manufacturers.
