SN74F32NE4

Overview

The SN74F32NE4 is a quad 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features an operating temperature range of 0°C to 70°C. The device utilizes a 14-pin PDIP package. Electrical characteristics include a high-level output current of -1mA and a low-level output current of 20mA at VCC = 4.5V. Propagation delay times are specified as 2.2ns to 6.6ns for tPLH and 2.2ns to 6.3ns for tPHL at VCC = 5V.

Feature Summary

• Contains four independent 2-input OR gates performing Boolean functions Y = A + B
• Provides standard TTL logic levels with defined input and output voltage thresholds
• Designed for through-hole mounting in a 14-pin plastic dual in-line package

Applications

• Digital logic circuit design requiring basic OR operations
• Signal routing and selection in electronic systems
• General-purpose logic applications in commercial temperature environments

Procurement Notes

Verify the component status, as catalog listings may indicate active production while specific ordering suffixes or distributors might show obsolete status. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range meets the application requirements. Check for RoHS compliance if environmental regulations apply. Validate that the manufacturer's warranty terms align with procurement expectations.

Selection Notes

Select this component when a quad 2-input OR function is needed in a through-hole DIP package. Consider the F-series speed and power consumption relative to other logic families like LS or HC. Verify that the 5V supply voltage is compatible with the system design. Ensure the 0°C to 70°C operating range suits the deployment environment. Compare pinout compatibility with existing designs if replacing similar devices.

Part Context

The SN74F32NE4 belongs to the SN74F32 family of quadruple 2-input positive-OR gates. It is part of the F/FAST series, known for higher speed compared to standard TTL. The 'N' suffix denotes the plastic DIP package, and 'E4' indicates lead finish and environmental compliance. This device is a catalog product from Texas Instruments, distinct from the military-grade SN54F32 variant.

Replacement Considerations

SN74F32N is a direct replacement with identical specifications and packaging. SN74F32DR offers the same logic function in a surface-mount SOIC package. SN74F32NSR provides the function in a small-outline package. Verify pinout compatibility and thermal characteristics when substituting packages.
