SN74AC08N

Overview

The SN74AC08N is a quad 2-input positive-AND gate manufactured by Texas Instruments, belonging to the AC logic series. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. The device features a propagation delay of 7.5ns at 5V and provides symmetric output drive currents of 24mA for both high and low states. Packaged in a standard 14-pin PDIP format, it accepts input voltages up to 6V, ensuring compatibility with various digital logic systems.

Feature Summary

• Executes Boolean AND functions using CMOS technology with push-pull outputs
• Supports extended supply voltage operation from 2V to 6V
• Accepts input voltages up to 6V regardless of supply level
• Provides high-speed performance with 7.5ns typical propagation delay

Applications

• Digital logic circuits
• LED driving applications
• Digital signal processing
• Control and automation systems

Procurement Notes

Verify the specific part number suffix against official Texas Instruments documentation to confirm package type and temperature rating. Ensure the component meets RoHS3 compliance requirements if applicable to your manufacturing standards. Cross-reference datasheet electrical characteristics with system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a wide 2V to 6V supply range is required compared to fixed 5V logic families. The AC series offers faster switching speeds than HC variants while maintaining CMOS power efficiency. Verify that the 24mA drive capability matches load requirements and that the 14-pin DIP package fits the target PCB footprint.

Part Context

This device is part of the broader SN74AC family of high-speed CMOS logic gates. It shares functional similarities with other quad 2-input gates like the SN74AC00 (NAND) but implements AND logic. The 'N' suffix specifically denotes the through-hole PDIP-14 package variant, distinguishing it from surface-mount options like the NSR or NDR suffixes.

Replacement Considerations

SN74ACT08N: Offers similar functionality with TTL-compatible inputs and a narrower 4.5V to 5.5V supply range.
