SN74ACT08D

Overview

The SN74ACT08D is a quadruple 2-input positive-AND gate from the Texas Instruments ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features low-level output current of 24 mA and high-level output current of -24 mA. The device exhibits a propagation delay of 10 ns and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a 14-pin SOIC format, it provides four independent AND gates with eight inputs and four outputs.

Feature Summary

• Contains four independent 2-input AND logic gates
• ACT series performance with 10 ns propagation delay
• High drive capability with 24 mA output currents
• Wide industrial temperature operation range

Applications

• Digital signal processing systems
• Microprocessor-based control circuits
• Memory interface logic

Procurement Notes

Verify the specific suffix D indicates the SOIC-14 package configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits for reliable performance.

Selection Notes

Select this component when ACT series speed and standard CMOS compatibility are required. The 14-pin surface mount package suits automated assembly processes. Verify that the 5V supply constraint aligns with system power rails before integration.

Part Context

This part belongs to the SN74ACT family, which bridges TTL and CMOS technologies. It offers faster switching speeds than standard 74LS devices while maintaining compatible input/output characteristics. The quad AND gate configuration is standard for general-purpose digital logic applications.

Replacement Considerations

SN74ACT08DR is a tape-and-reel variant of the same functional device. SN74ACT08N is the PDIP-14 through-hole equivalent. Cross-reference datasheets to confirm pinout and electrical parameter compatibility.
