SN7432N

Overview

The SN7432N 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 4.75 V to 5.25 V. The device features four independent OR gates, each with two inputs. It is housed in a 16-pin PDIP package designed for through-hole mounting. The component supports a wide operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input OR logic gates
• Standard TTL-compatible logic levels
• Through-hole DIP-16 packaging

Applications

• Digital logic circuit design
• Signal combination and routing
• Basic Boolean logic implementation

Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the PDIP-16 package matches your PCB footprint requirements. Check RoHS compliance status if required by your manufacturing standards. Ensure the supply voltage aligns with your system's 5V logic level specifications before procurement.

Selection Notes

Select this component when a simple OR function is required for digital signals. It is suitable for general-purpose logic applications where standard TTL performance is sufficient. Consider alternative packages or logic families if higher speed or lower power consumption is needed. Verify pin compatibility if replacing existing designs.

Part Context

This component is part of the widely used 74 series logic IC family. It provides basic logical operations essential for digital systems. The SN7432N specifically implements the OR function across four separate channels. It serves as a fundamental building block for more complex combinational logic circuits.

Replacement Considerations

Compatible substitutes include other manufacturers' SN7432N equivalents or generic 74LS32 variants. Ensure any replacement maintains the same PDIP-16 package and electrical characteristics. Verify pinout compatibility to avoid redesigning the PCB layout.
