SN7432NG4

Overview

The SN7432NG4 is a quadruple 2-input positive OR gate manufactured by Texas Instruments. It belongs to the standard 74 series logic family and operates within a supply voltage range of 2 V to 6 V. The device features a propagation delay of 17 ns at 5 V and supports a high-level output current of 0.4 mA. It is housed in a 14-pin Small Outline package (SOIC) with a width of 0.295 inches.

Feature Summary

• Contains four independent 2-input OR gates for parallel signal processing
• Provides positive-OR logic functionality for digital circuit design
• Compatible with standard 5 V logic systems

Applications

• Digital logic circuits requiring OR operations
• Signal routing and selection networks
• General-purpose combinational logic designs

Procurement Notes

Verify the component marking against the official datasheet to confirm authenticity. Ensure the package type matches the required PCB footprint. Check for RoHS compliance status if environmental regulations apply to the assembly process. Confirm the operating temperature range meets system requirements.

Selection Notes

Select this component when a quadruple 2-input OR function is needed in a small outline package. Consider the 17 ns propagation delay for timing constraints. Verify that the 0.4 mA output drive capability is sufficient for the connected load. Compare with other 74 series variants if different speed or power characteristics are required.

Part Context

This part is part of the broader 74 series logic family, which includes various logic functions such as NAND, NOR, and flip-flops. The SN7432 specifically implements the OR function. It is commonly used in educational kits and industrial control panels where standard TTL-compatible logic levels are utilized.

Replacement Considerations

Equivalent parts include SN74LS32N and SN74HC32N. Verify pin compatibility and electrical specifications before substitution.
