SN74F260DR

Overview

The SN74F260DR is a dual 5-input NOR 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 5.5ns at 5V with 50pF load. The device provides high-level output current of 1mA and low-level output current of 20mA. It functions in an ambient temperature range of 0°C to 70°C and is housed in a 14-SOIC surface-mount package.

Feature Summary

• Dual-channel architecture containing two independent 5-input NOR logic gates
• High-speed switching capability with specified propagation delay characteristics
• Robust output drive strength supporting standard TTL loads

Applications

• Digital logic processing circuits requiring multi-input NOR operations
• Microprocessor interface systems for address decoding or control logic
• General-purpose digital signal gating and masking applications

Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the tape-and-reel packaging format and SOIC-14 physical dimensions. Confirm that the component meets RoHS compliance standards as indicated by manufacturer documentation. Ensure the supply voltage provided matches the 4.5V to 5.5V operational range to prevent device malfunction.

Selection Notes

Select this component when a design requires two separate 5-input NOR functions within a single package. Consider the 14-pin SOIC footprint for surface-mount assembly constraints. Evaluate the 5.5ns propagation delay against system timing requirements to ensure adequate speed performance for the intended application frequency.

Part Context

This part belongs to the Texas Instruments SN74F series, which utilizes Fast Schottky transistor-transistor logic technology. The F series is characterized by higher speed performance compared to standard 74LS counterparts while maintaining compatible pinouts and logic levels. The SN74F260 specifically addresses needs for complex NOR logic integration in high-speed digital environments.

Replacement Considerations

Compatible substitutes include SN74F260N (DIP package) and SN74F260D (SOIC package). Verify electrical specifications and pinout compatibility before substitution.
