Overview
The SN74F32N is a quad 2-input positive-OR gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features a propagation delay of 5.6ns at 5V with a 50pF load. The device provides an output high current of 1mA and an output low current of 20mA. It supports logic levels with a maximum low input voltage of 0.8V and a minimum high input voltage of 2V. The component is housed in a 14-pin DIP package and functions reliably across an operating temperature range of 0°C to 70°C.
Feature Summary
- Contains four independent 2-input OR gates for parallel signal processing
- Provides push-pull outputs capable of driving standard TTL loads
- Operates on a single 5V power supply rail
Applications
- Digital logic circuits requiring logical OR operations
- Signal routing and selection systems
- Data bus enablement and control logic
Procurement Notes
Verify the manufacturer marking matches Texas Instruments specifications. Confirm the package type is 14-pin PDIP. Check for RoHS compliance status if required by project standards. Ensure the operating temperature range meets environmental requirements. Validate pinout compatibility with existing PCB footprints before integration.
Selection Notes
Select this component when a quad OR gate configuration is needed in a through-hole DIP package. It is suitable for designs requiring standard TTL logic levels and moderate switching speeds. Consider alternative packages like SOIC or TSSOP if surface-mount technology is preferred. Verify that the 20mA low-level output current meets the fan-out requirements of connected inputs.
Part Context
This part belongs to the SN74F series, which represents fast TTL logic family components. It serves as a direct functional equivalent to other manufacturers' 74F32 parts. The device is widely used in legacy digital systems and educational electronics projects. It complements other SN74F series gates for complex combinational logic design.
Replacement Considerations
Direct substitutes include the SN74F32PC from onsemi. Parameter-equivalent options are available from various logic families such as SN74LS32N or SN74HC32N, though electrical characteristics may differ.
