SN74F32DRE4

Overview

The SN74F32DRE4 is a quad 2-input positive-OR gate from the Texas Instruments SN74F32 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 3.8 ns. The device provides a low-level output current of 20 mA and a high-level output current of -1 mA. It is housed in a 14-pin SOIC package and supports surface-mount installation with an operating temperature range of 0°C to 70°C.

Feature Summary

• Contains four independent 2-input OR logic gates
• High-speed bipolar operation with 3.8 ns propagation delay
• Robust output drive capability with 20 mA low-level sink current

Applications

• Digital signal processing circuits requiring logical OR operations
• Data routing and selection logic in embedded systems
• General-purpose logic functions in industrial control equipment

Procurement Notes

Verify component authenticity through authorized channels, as this part number is discontinued. Confirm that the specific revision matches design requirements, noting that end-of-life status may affect long-term availability. Ensure compliance with RoHS directives if applicable to the target assembly process.

Selection Notes

Select this component for applications requiring standard TTL-compatible OR logic with moderate speed. Consider alternative packages or series if lower power consumption or wider voltage ranges are needed. Verify pin compatibility when replacing older designs with updated revisions.

Part Context

This component belongs to the SN74F32 family of quadruple 2-input OR gates manufactured by Texas Instruments. The 'D' suffix indicates a 14-pin SOIC package, while 'RE4' denotes tape and reel packaging with lead-free composition. It serves as a fundamental building block for combinational logic circuits.

Replacement Considerations

SN74F32DR is listed as a direct substitute.
